Absolutely there should be less death in comics!!!
Specially gods. I was unhappy with Sentry killing off gods (specially since he made it look like it was nothing) but now that i look back if you kept it to just that i would be ok with it. I even like the idea od a God Butcher but i do think it should be harder to kill a god and death should be used less in general.
I believe Gods should be like the movie "The One" If one dies then the others should gain the fallen one's power (until the fallen rises again) bc that's also the only beings that i think should be able to come back from the dead are the gods. Anything considered less then a god type should not be allowed to come back to life (unless that is their mutant ability)
