To that en, Kudos to Meyer for wanting to leave it more open-ended.
Well, Meyer said he did not add the torpedo on Genesis. That was Bennett.
As for life from death, they also said it destroys the original life to be replaced by new different life. But you make a point I never associated with Spock death in that movie. I never took it as a way out. And I was too young to know Nimmoy was rumored to want out.
