He died of old age complications to be sure, but not a veggie. Plus I think he actually did lead well and would had tried to avoid politics... especially those that corrupted Earth to the point that it had.
Not to squash your ideas... that's just not what I had in mind for him.
I'm starting to write a main story for Minimal G that will bring these guys to life better. Just give me some time there.
