Daniel Jackson: Characteristics And Motivations
Peaceful Explorer, Reluctant Warrior
Daniel is a natural explorer, and his thirst for knowledge knows few boundaries. While he initially undertook the post at the SGC as a means to search for his kidnapped wife, the thrill of discovery kept him going during the ordeal and after her death.
As the years went by and the Goa'uld were superseded by even worse enemies, from Replicators to Anubis to the Ori, there is no question Daniel lost some of the idealism that had driven him. He became more cautious about trusting the motives of others, more willing to act first, and more willing to destroy those who had shown themselves to be enemies. His patience for negotiation decreased. His thirst for knowledge was still key, but he was willing to use his skills to attain technology to protect humanity, rather than for a higher purpose. This was very evident during the quest for Merlin's weapon (10.10 "The Quest Part 1", 10.11 "The Quest Part 2"). In the fight against the Ori emerged his willingness to lie to and deceive his enemies, as he did to Adria (10.14 "The Shroud"). He endorsed using the Ark of Truth to supplant the beliefs of a galaxy of worshippers with a truth more palatable to Earth, that the Ori were evil. Clearly he believed he was freeing an enslaved people, but it's hard to imagine the Daniel of ten years earlier doing so without evident contemplation (Stargate: The Ark of Truth).
His general indifference to his own personal safety and his sometimes unreasoning hatred for the Goa'uld have also caused him to engage, extremely recklessly, in 'snake-baiting' or mouthing off to the Goa'uld as well as physically seeking to thwart them. Such actions have earned him more than one back-hand (2.09 "Secrets", 3.13 "Devil You Know").
However, while he might hate the Goa'uld with an unreserved passion, he has also demonstrated he is capable of putting aside his personal prejudices for the greater good of the mission and his other team mates. While he may be heedless of consequences to himself he does not knowingly endanger anyone else through thoughtless or reckless actions (Stargate the Movie, 2.17 "Serpent's Song", 3.3 "Fair Game", 3.06 "Point of View", 4.22 "Exodus", 5.15 "Summit Part 1", 5.16 "Last Stand Part 2").
Moreover, it is likely that his first-hand experience of the absolutely corrupting influence of the Goa'uld racial memory given to him in a dream by Shifu (4.17 "Absolute Power") caused him to question the wisdom of allowing his hatred to poison his soul. That he has considered modifying his position seems to be indicated by his response to Teal'c in which he said if Apophis were delivered into his power rather than succumbing to the desire for revenge, he hoped he would be able to chose the more rational option (4.22 "Exodus").
Making Friends And Influencing People
He is adept at turning enemies into friends, and in fact has succeeded in taming more than one 'savage beast' and making an extremely favorable and influential impression on many of the aliens the team has encountered (1.04 "Emancipation", 1.06 "The First Commandment", 1.10 "Thor's Hammer", 1.16 "Cor-Ai", 1.13 "Fire and Water", 1.17 "Enigma", 2.06 "Thor's Chariot", 2.07 "Message in a Bottle", 2.09 "Secrets", 2.13 "Spirits", 2.18 "Holiday", 2.19 "One False Step", 3.20 "Maternal Instinct", 4.05 "Divide and Conquer", 4.08 "The First Ones", 4.9 "Scorched Earth", 4.21 "Double Jeopardy", 7.07 "Enemy Mine", 7.10 "Birthright", 8.05 "Icon") not to mention two alternate versions of people he knows well in our reality but who had never met him (1.20 "There But For the Grace of God", 3.06 "Point of View"). He's also very good at recognizing when apparent friends are not what they seem (4.02 "The Other Side").
He takes his responsibilities as an explorer very seriously when it comes to dealing with the consequences of his interactions. When the arrival of SG-1 to the Rand Protectorate set off a religious uprising, Daniel insisted that Jack allow him to go back to the planet and try to head off a collapse of the government. While he did not succeed in stopping the rebel takeover or subsequent world war, he instilled hope in the survivors, helped them defeat the zealots, and promised the SGC's help in rebuilding their country (8.05 "Icon").
His view of morality drives his diplomatic efforts. His first step is always to try to see the other side's point of view and attempt to make them see Earth's. However, he refuses to renounce his morality either to save his life or to pacify a foe. Faced with the Doci and his Origin-based view of the single path to enlightenment, Daniel asserted his belief in free will and his willingness to die rather than give up that belief (9.03 "Origin Part 3").
Sometimes his belief in others' morality leads him to overestimate their capacity for doing the right thing. His desire to help Jarod Kane end his planet's civil war led him to be taken prisoner, and the subsequent effort to rescue him and stop the Ori's interference cost the SGC lives and a ship. In the end, the deal Daniel brokered did not hold, and the two warring nations destroyed themselves. Daniel's resigned disappointment was palpable (9.15 "Ethon").
Loss, Grief And Failure
He appears embarrassed when receiving praise, as if he doesn't like to be the center of positive attention (7.04 "Orpheus", 7.07 "Enemy Mine"). At the same time, since his return from ascension, he seems to have come to terms with his life, to believe that finally he has found his place in the world (7.04 "Orpheus").
When it comes to grief and personal loss, Daniel often keeps his feelings to himself, though there is no question he feels losses deeply. In his dream of Sha're's death, he was reluctant to discuss his grief with his teammates and tried to keep from crying in front of them. Rather than turn to them for comfort, he decided to leave the SGC (3.10 "Forever In A Day").
After witnessing the death of his friend and doctor, Janet Fraiser, Daniel again sought no comfort, grieving quietly and alone in the room where she had tried to save him from radiation poisoning. Yet he turned his grief into concern for Janet's legacy, in the end insisting that the video of her death be made available to the documentarians. He overcame his own sorrow to help Airman Wells deal with his feelings of guilt over Janet's death, and he was there to help welcome Wells' daughter Janet into the world, again honoring Janet's life and what she meant to him. In all those events we never saw him seek comfort from anyone, though we hope it was given at some point (7.18 "Heroes Part 2").
His frustration and sense of failure were perhaps never stronger than when he came to believe there was no Earthly way to defeat Adria and the armies of the Ori. Knowing Morgan Le Fay could do something but wouldn't due to rules he found reprehensible, Daniel told her he had "had it". He rallied to demand her help, then wept in hopelessness when she refused to offer more than the merest assistance. Ultimately, it was enough for SG-1 to do the rest (Stargate: The Ark of Truth).
Reverence For Life
This android encounter did not change Daniel's inherent respect for life in all its various forms. When SG-1 discovered the android Reese, he immediately related to her as if she were a human being. Her childlike innocence both charmed and alarmed him when he discovered that she was the creator of the Replicators, but he strove valiantly to create a sense of trust between them in order to get her to shut her "toys" down before they destroyed his planet. This consequently led to deeply painful angst between himself and Jack when the colonel shot Reese to prevent a take-over of the base and the planet by her Replicator bodyguards/army (5.19 "Menace").
When frustrated, he has also been snarky with Bill Lee, referring to him as the 'bottom of the barrel' (9.04 "The Ties That Bind") and implying Bill had not yet done anything to warrant respect at the SGC (9.10 "The Fourth Horseman Part 1"). He's also aimed his snarkiness at Mitchell, yelling "New guy!" at him when Mitchell touched an alien device too hastily (9.09 "Prototype").
While he still tends to give others the benefit of the doubt on first contact, he is quicker to realize when he is being taken advantage of and to assert his own will. He is also less likely to waste his breath trying to change the mind of an opponent, quicker to recognize when such attempts are hopeless. For example, he knew from the start that Replicator Carter could not be turned from her objectives by anything he could say, so that his only option was to fight her (8.16 "Reckoning Part 1", 8.17 "Reckoning Part 2"). In a more humorous vein, he quickly lost patience with his faux hostages in the museum of P4M-328. Rather than try to reason them out of their fear, he lost his temper and told them all to shut up (10.16 "Bad Guys").
