Remember: Justin Foley let his girlfriend get raped by Bryce. Didn’t tell her about it; made her think she was crazy – resulted in her hanging out with her rapist. Wanted to murder Clay. Took the picture of Hannah and let it get out.
Justin Foley is an awful person and having a Hollywood abuse trope (abusive father), and him shedding crocodile tears doesn’t change a thing. Nothing will ever change that.
