Hey Hulkout42,
I get where you are coming from and you have an understandable position given a), from your username I guess you are a Banner fan and b), as I have been saying the writers aren't doing a very good job of making Clint's position one that it is sympathetic. However I'd like to address your points.
1) I'll take your word for this as I haven't read any of those comics.
2) The panel argument doesn't really hold water with me. If you have read The Accused it clearly and unequivocally shows that Clint saw green flickering (note that I don't think that means that Banner was Hulking out). If anyone is looking at this issue with an open mind you at the very least have to consider this fact.
3) For me assisted suicide is nothing like murder. I respect that you have a different opinion though.
4) I disagree with the premise and conclusion you've jumped to (e.g. point 3) but I do agree there is a lot he has to do to be 'redeemed' and basically the forgiveness of those four you mentioned would only be a start. But, I also think the forgiveness from Banner goes both ways as he has put Clint into a difficult situation.
I also think that you have cherry picked your facts a bit as you have ignored any that might support Clint's decision or taken the most negative view possible on any of his actions.
Anyway I want to thank you for your post, I know it is irrelevant to you whether it was liked or not but for me it is one of the best posts in the thread. Over the last week or so I've changed my mind often on this whenever I've given it any thought. After reading this I've categorically ruled out the 4th option (No - not even close), it is probably not what you intended but it what it is.
