Question!

Would you, as a fan, still have respect for the Batman if he killed Killers? Don't answer as a fanboy, answer as a fan, Joker Kills Alfred, and Batman kills Joker for it. Would you still support him the way you always have?

If it was a revenge killing, then no. If he killed to save a life, then yes.

I'd definitely still support him, especially if The Joker killed Alfred; I couldn't blame Batman for going apeshit after that! Plus, it'd make for an interesting story. The only problem is getting killed would probably be what The Joker wanted, because he wants to push Batman/corrupt him, etc.
