So ellie had no problem, murdering half the population but somehow it was so difficult to kill Abby.

Nobody working on the story had actually thought to themselves that maybe it isn’t such good idea to have the character slaughter half the population for their revenge just to change their mind last minute??

And it’s not your usual “it’s okay cuz their henchman “ No the game actually makes you see them suffer. If you shoot somone in the leg you hear them wailing .

It was somehow traumatizing to kill people personal vendetta against but not people who were for the most part innocent.
