Insurgent: How do different Characters respond to the Conflict

The characters in Insurgent respond to the conflict very differently. For example, Tris and Tobias respond by running headfirst into it, they don't think about the consequences much. That's how I would do it, it helps save you from becoming too nervous, just like Tris's brother Caleb. He always is scared and he refuses to cooperate at first. Wow. He wouldn't even risk his life to save the world from the Erudite. One life isn't as important as many.
