You can legally kill someone in self defense, even as a civilian.
I'll weigh in on that one, having done advanced Criminal law last year.
B:TAS is completely correct, and what's more in certain circumstances you can kill in defence of another e.g. Joker puts a gun to Robin's head, and tells Bats he's going to shoot on the count of 3, 1....2.... Batman throws a batarang that slits Joker's throat, Joker dies.
Sure, Bats might be charged, but it would be such a clear cut case of self-defence/defence of another that he'd most certainly beat the charge.
If you don't believe me, read this :

assuming that Gotham city is probably most analogous to New York,
from a legislative point of view.
I used the same logic to defend Superman's killing of Zod in MOS, against people suggesting that he "murdered" Zod. Clearly he didn't, not in a legal sense. ( of course in that situation a few common law defences, like necessity might also apply).
In the same way it would have applied way back in the day when the Flash killed the reverse Flash (the first time) who was about to kill Iris.
The legal defence of self-defence would apply in such a situation. Now if Bats goes out looking for the Joker, and without a "how d'you do?" cuts his giggling head off (which we'd all like to see, I imagine), well that would be murder.
Some of the comments around us all being okay with soldiers and cops killing, well to be honest that has a lot to do with the fact that our culture and government tell us that its okay. We're kind of conditioned to believe that stuff (like murder is wrong, which is important, because if we didn't society would fall apart). Now I personally believe in the death penalty, but at the same time I'm also very wary of statements like this....
Only the state can give people permission to kill.
Police in the line of duty. Soldiers during war. The death penalty.
If Batman kills, he does so outside of the law and he will be considered a murderous criminal.
I'm not saying you're wrong, because technically you're absolutely right. But, the bigger question is whether the state having the sole monopoly on killing is a good thing ? Who knows, it's such a complex question ? I certainly don't know the answer.
However, I agree with this.....
I think Batman cares about the people in Gotham. If he didn't care you'd see a lot more collateral damage.
I just think he cares about putting on a costume and beating the crap out of people a whole lot more.
Bruce Wayne could pepper Gotham with teen reform centers and job programs. That money is instead invested in things like shark repellent Bat Spray.
True ! If Bruce really wanted to reduce crime he'd invest in the city, or get behind a politician who would clean up the corruption. There's a lot he could do, but doesn't do, that's bound to be more effective -and long lasting- than kicking the crap out of a few bad guys.
However, that doesn't make for exciting comic book reading.
It's great that the issue has grown to become about whether Batman should kill, and killing by non-state-sanctioned people. There's not going to be any final answer that will please everyone, but it's cool hearing true Bat-fans sharing their thoughts.
Even if we think it's wrong, sometimes Batman killing someone can be kind of satisfying, from a story point of view like this......
