I am having trouble on deciding how my characters should act for a novel-novella called The Runaways. It is about a group of five men who have come back to Earth after escaping hell when hell's defenses went down. They go into hiding, but Hell is on their trails and hellish creatures and machinery take them back down one by one, except for one man who wants to confront God and tell him that he's actually innocent. One problem: I have no idea how people from hell would act, behave to others and each other, or how they would say to people in public. Would they be cruel? Quiet to hide their identity? I could really use some help, I have no idea how somebody like this could act.
