Genis-Vell Vs Black Bolt Vs (God like) Cable or Nate Grey

Well the Purple man, with the help of the Overmind, in Purple Reign was a beast that, in Genis' words, "he was opening thousands of spatial rifts at the same time!" . . . . and a slight glimpse of the Cosmic Awareness reduced him into a fetal position.

did genis die?? if so how??
i think he had that much knowledge that his mind couldn't settle and it sent him insane? is that true?? was he a villian at that point?

not a villain as such, just a very enthusastic vigilante/god.
