Okay, I have this character who is a part of a resistance team. He's one of the top ranking individuals within the group, due in part to his family being in the resistance for generations. But this character doesn't enjoy being a part of the resistance; he just wants a calm and uneventful life. Though right before the end, the resistance gets cracked down on and I want him to betray the group in exchange for some kind of deal to live peacefully. The problem is, I can't come up with a reason why he would not have done this sooner. Should I show him to have doubts about this action? I want the reader to dislike this character but at the same time understand his motivation for doing this.
