[Harry Potter] Is Avada Kedavra legally allowed in cases of self-defense?

Just an hour ago someone broke into my house and attacked me! I'm a slightly above-average wizard who used to work as a Defense Against the Dark Arts teacher (retired now) and the only thing I could think of was to cast Avada Kedavra. Now I'm thinking maybe that wasn't the best thing to do... "Unforgivable" and all...

I can prove without a doubt that it was in self defense. Do you think the Ministry will allow me this one time, since my life was literally in danger? Or am I going to Azkaban? Please help. :(

Probably not. Just like in the real-ass world there are laws against using enough force. There were hundreds of ways you coulda dealt with an attacker. If memory serves that particular curse only works if you WANT to kill. You WANT them dead.

Perhaps arguable if you come upon them after murdering your family, but for startled self defense it's hard to argue WHY you could even cast this particular curse. Why did you want the dead? It's arguable death is a very permanent way to make sure they can't hurt you, but there's lots of alternatives for a slightly above average wizard to completely disable an opponent eh?
