Terry, you asked for our opinions as to what we thought the verdict, would or should be. I answered. Please don't take my comments as a negative on your story in any way.
Actually, I'm more annoyed with Clark over his treatment of Lois than I am with the fact that he killed Bill Church.
You spoke of 'my' Superman, and 'your' Superman and that he really doens't belong to any of us. Technically that is true, but as the author of a story, the character (even if he/she is borrowed) is 'yours' for that period of time. You utilize the traits and characteristics you want to to facilitate your story. This is fiction, and there are no absolutes, with that I agree.
You are a terrific writer, and I will read most anything you write (except maybe Lois and babies). I don't have to agree with every part of your story, or even like it, to be able to enjoy it. I'm along for the ride and am looking forward to how you resolve the situation you've placed our favorite characters in.
Tank (who reminds all writers that you want your readers to have an emotional response to your story be it positive or even a bit negative... the worst case is an indifferent reader)
