That's not self-defense. That's a separate legal standard colloquially known as the fleeing felon rule which isn't nearly as well-supported in ethics and beyond that has varying legal application when it comes to private citizens.

There's also separate case law and ethical debate on believing someone to be an inevitable and unavoidable threat, such as with battered spouses, but I am not surprised cape comics don't want to wade into either of these issues very often.

Now all this is an entirely separate matter as to whether a jury would convict a citizen gunning down your average supervillain (they wouldn't) and whether an ethical argument could be made to defend people taking matters into their own hands (it could).

It is however a bit nonsensical that villains never get popped by an off duty cop or something when in the middle of criming. That said, IIRC Gotham at least doesn't actually allow private carry by civilians. No 2nd amendment in DC I suppose. So that might just be explained by there being significantly less guns in the hands of civilians than in the real world.
