Is he....prepping to sacrifice others when the aliens come? Being the best human physique on Earth isn't the goal, because he gloats over people not in the competition. It's not apparently about being the fittest for mating purposes. He's not indicating he's running a compound/cult/family. His goals are beyond my comprehension, I guess. Unless he's just living for spite and everyone who is clearly not good enough at having a body reminds him that he is good enough. But that's not a goal either.
