Not really -- but you seem to think it's okay to steal and be a scum-bag. If someone is going to potentially ruin my life I will kill them, yes, absolutely. You wouldn't?
Lets say I'm going to burn down your house, bomb your car, wipe out all funds from your bank account, ruin your credit history to the point where you can't recover, and enter false data into your criminal record so you can't get a decent job. Don't ask how... lets just say I could do it. The only way you can stop me is to shoot me. Would you?
What if I was just in your house robbing you? Lets say you had a gun and I didn't. I wasn't stopping... you couldn't ID me, and you knew the police weren't there. Lets say it was something important and you CAN'T replace it. So, I should be allowed to walk away?
Now... where do you draw the line, and how? Thats the question where there is disagreement. I don't think he SHOULD have killed the guys -- done something about it if he could, yes. Fact is, he did kill them -- but he was just protecting his neighborhood. You have to draw the line somewhere.
