I just hate Skylar because she sang happy birthday uncomfortably and it legit made me not like the character ever again lol

People hate Jenny the most because they probably have seen a Jenny in their lives. Joker, Hannibal and Vader are too removed from normal life to genuinely hate.

I wouldn't put what Skylar did anywhere on Jenny's level.

That said, Jenny's trauma was a lot worse and affected her over her entire life.

Yeah, I can't understand anyone who doesn't come away with a deep sorrow for her character - certainly compared to infinitely lucky forest. She tries so hard to be a good person despite everything awfull happening to her every single time, he just does what he feels like and every time he has the best luck ever.
