When someone is defending himself by shooting at someone with a weapon. The enemy doesn't necessarily has a weapon, there may be a certain threat for the person defending himself.
So, we have a person who wants to defend himself by shooting at someone or an animal.
Is there a word or phrase in English that would describe this situation precisely?
I thought of 'shooting back' or 'firing back' but it's not clear from the definitions in some dictionaries whether I can use any of these in my situatuion.
EDIT:
I'm trying to translate a story which is about a man being under drugs who sees creatures and wants to shoot them (they are angels). It has a catchy title which I'm trying to translate as accurate as possible. Since they're angels and he is being overdosed I want to preserve the whole meaning of the story in the title (It's not being said but I think they want to take him with them).
It's a fiction, no need to bind it with laws.
Would 'shoot out at angels' fit?
