I'm talking about rules that are common, it doesn't mean that every superhero follows them, but certainly many of the most important superheroes do.
The Punisher happens to be a bit of an anti-hero, as far as I know? So he doesn't count.
Second, fetuses aren't people.
That's your opinion, and I'm curious how far the superhero rules are consistent, do they reach human fetuses?
In other words: For superheroes, is a human fetus lower than a criminal?
