I'll start off by listing mine:
The T-800, Terminator 2: "I know now why you cry, but it's something that I can never do." Gets me every damn time.
ADA, Zone of the Enders: I think I'm the only one who played this game more than the MGS2 demo that came with it. I will never not laugh at the exchange of "You may speak like a human, but you're still a heartless computer, aren't you?" "That is correct. What is the problem?"
Codsworth, Fallout 4: He survives the nuclear holocaust despite not having a bunker and waits 200 years for you to come back. When you look at what changes his relationship with you, he mostly just wants you to be nice to people. I never swapped him out as my companion.
B.O.Y.D., Ducktales 2017: He's adorable. 'nuff said.
oh yeah, in context for sure. I just wanted to point out that this act of ending a life isn't even performed as a very active one, more as a passive one. And still it doesn't take away from her agency since her original 'programming' would presumably dictate her to lower the blade before he runs into it, which she doesn't do. So, she ultimately proofs her consciousness/independent will through a non-action which is also a self-defensive action that leads to the death of her creator. Idk, I just really liked that play with passivity/activity, so I felt like highlighting it, clumsily. Idc about the legal distinction or whatever
