[DC/Superheroes in general] Why is Batman's "I don't kill people" approach to vigilantism considered special? Aside from a few select cases, I'm pretty most vigilantes and heroes never straight up murder the bad guy.

Depends on the version, but Batman often has this fear that if he kills once, he'll find it easier to kill the next time, and the next. Many other heroes have a no-kill rule simply because they don't want to kill, and sometimes they break it for good reasons; Batman tends to emphasize this rule more than others because he's got some intense psychological reasoning behind it, and can't afford to bend it. (Unless it's Darkseid.)
