[Harry Potter] What is it that makes Avada Kedavra so bad when there are so many other spells which are equally lethal?

Avada Kedavra is for killing. That's all it does. It's not even comparable to a gun, because a gun can be used for things like target shooting or hunting or self-defense. The Killing Curse, like the other Unforgivable Curses, only really works if you mean it, if you really and truly want someone to die.

(Now consider how casually Voldemort was able to use it.)
