inFAMOUS 2 at the ending has an interesting one.
In the good ending, Cole admits that he's afraid of death but goes along with it anyway. If we assume Good and Evil Cole are the same person (close enough), it suggests that in the evil route he was scared enough of death but also had enough disregard for others to not go through with the sacrifice.
All that talk about "not knowing the RFI would cure the plague" was bullshit, too, because it's mentioned that was the original purpose of the RFI and that it absorbs ray sphere radiation, the cause of the plague.
The point I'm trying to make is that in the evil ending, Cole goes through all these mental gymnastics to justify staying alive, and on some level he knows the gymnastics are all bullshit. By trying to make the morality in the game more gray, Sucker Punch wound up making it even more black and white, but in a cool way.
The world will NEVER have enough superhero sandbox games. It's my favorite subgenre.
