In Infinity War, Thanos implies that the reason that he wants to kill half of all life is because life generally grows beyond its means. That is, if too many people are alive, then their will go beyond what their natural resources can comfortably maintain.
However, it is clearly stated that once he has the completed Infinity Gauntlet he is the most powerful being in the universe. Shouldn't he be able to just create more natural resources.
Why doesn't he just use his massive power to fix the problems that made him want to kill half the universe?
