spoilers if you haven't read Hulk the end or Punisher the end.
I just mean, Hulk the End was about how he is being punished for man's knowledge of the atomic bomb and spending all eternity alone, except for the flesh eating roaches who eat his flesh contantly, since no one is alive on Earth. And he can't even kill himself because he turns into the Hulk right before he does.
Punisher killed everyone and then sets himself on fire.
Couldn't their end be light hearted and happy, epic but not depressing.
