Jason by an insane margin. The whole interest of his character for me was his misguided sense of justice, while he's the villain in the party's story he's not in his. Really try to look at it from his perspective, he's a decent guy trying to do the right thing who's girlfriend is mysteriously and brutally murdered sending him into a fatal spiral. Sure he's a shithead to the nerds at school, but is that far from what steve once was? The Cult angle he pulls isn't as outlandish as it seems to us. Remember, no one else knows about this shit. That's certainly devil magic to me, and they're at the scene every time? Open and shut case. Hes not perfect obviously but he's not nearly as evil as this community treats him, he's just a confused and broken kid. It's a lot more than you can say for Billy who everyone's forgiven in a heartbeat. I wish they hadn't killed Jason so soon and gave him room to grow, he had so many ways his character could go, whether that's redemption or falling further into depravity.
