Okay, Jam, the only jerk*** thing Duncan has done this season was laugh at Scott and ask what Courtney thinks of him. Then Gwen broke up with him because of a supposed jerk*** thing they did a year ago, even though Gwen returned the feelings, mind you. Gwen even entered a rivalry against Courtney after that. Not to mention, Gwen also has shown to laugh at other people's misfortune just like Duncan (to a slightly lesser degree. Remember Evil Dread?).

The worst Duncan has done is bully Harold, and arguably scare the other campers into alliances, which aren't as "questionably immoral" compared to what Courtney has done.

Gwen broke up with Duncan because he was obsessed with Courtney in Moon Madness. That's what we're told, and that's what I'll assume. It was poorly written and making Duncan act like that in only one episode made me think that they just did it so they'd break up.
