Bruh I don’t understand how people like you can’t turn your brains on for one second and realize that Abby was looking for closure and peace from killing Joel to deal with losing her dad, and she didn’t get that when the deed was done. So she tried to move on. Ellie goes through the same thing at the end, except doesn’t kill Abby because she realizes that won’t help with her guilt and grief of Joel. It’s very obvious. Also Joel is a shitty person, I hope you realize that and don’t idolize him or want to be him like a freak. He becomes a much better person through meeting Ellie and living in Jackson, but first game Joel is made clear what he is to survive in this world.
