[Comics]Do superhero’s like Spider-Man and Batman enforce their no-kill rule on other superhero’s that do kill when they have to have to work them?

Batman does. ALso on heroes he *doesn't* work with. He's very anti-killing.

Others have their no-killing based on a genuine moral stance rather then a trauma reaction, and are slightly more flexible. Generally, it depends on the hero- the Punisher needs to be kept on a tight leash, but if Captain America says someone needs to die then you can assume he has a good reason. 

It depends a lot on the Heroes, but generally most of them will try to stop killing, but as long as it was a genuine desperate situation, they'll usually stick to just disapproving.
