>>92062725Punisher has been arrested and imprisoned alone before, and he gets out due to various reasons such as someone having a use for him or faking his capture. On top of that, the superheroes that object to his presence are the non-killing type to begin with, so they won't kill him and the ones that would kill don't mind him.
When Punisher goes up against most supervillains, he gets his ass kicked and doesn't get the shot unless they are absolutely irrelevant since he is just a really well trained guy with guns and killing them would render them unusable.
Finally, Punisher has a bunch of people who think he is the coolest shit in-universe because he is a normal guy fighting against crime in a shithole world, so even doing that won't stop copycat Punishers.
