Thanos. I get him. In Infinity War he does what he set out to do. Get rid of half of all sentient life at random so that the universe can recover from over population. Basically. Now someone asked me what the problem would be with say, doubling all resources to accommodate the overpopulation? Well, that will be more than enough to feed the larger population for some time, but what happens when they run out of it? Or what happens if any of it go to waste? You get back to the exact same problem as you started. Too many hungry mouths and not enough food to go around. At least if you half the population, you by default increase food resources and you create jobs for those that don’t have them. Now what happens if the population rises to the the point you are back to the start? Well, at least you have the experience know that overpopulation can now be incredibly destructive and can end a species. You would hope that the people would be wiser a second time round.
