Literature? That's a bit beyond my league, Tim, but I am flattered.
I don't see myself doing a religious protagonist, but I have had characters dabble in it. When Brad hooked up with Father Tim (Millennium), he let his mind wander down that road. I got some great input from Father Harry on how to frame that conversation, and it was pretty interesting.
Thanks. What I've tried to do with most of these characters is to give some sort of internal challenge to grapple with, and that inevitably runs into the moral/ethical/philosophical dilemmas. With Will, it's more interesting to me because he's evolving more rapidly. Sometimes people say they'll change, try to change, but never really change (like Brad with his control issues). But a guy who's almost 15 is more malleable. He can learn from his mistakes.
One of the biggest complaints I've gotten about Will is that his temper gets out of control. This isn't unusual for an adolescent male. Something I have some personal experience with. But I find that can fade pretty quickly as a guy matures, and I think that can happen to Will.
