> Self defense, as I pointed out, is a perfectly normal reason to kill someone which is widely accepted as a moral argument in court.

"I (accidentally) killed him, while trying to protect me." is very different from "Oh, killing is just (second) nature to me, I need the daily kick." When you need to have a serious threat to make you do something, then that thing is in fact not your nature.

> I think not.

I pointed out another example of that meaning of the word "nature" and you answered as if I made claims about morality of killing or slaughtering people/animals?

Sorry to me that felt very much like scope creep.
