Plot Hole: "Why didn’t Thanos just create more resources instead of killing half of life on every planet in Avengers: Infinity War (2018)?"

Explanation: "Is there not a scene explaining that he’d had the genocide idea for a long time, but was rejected and considered crazy by his people? I think the implication is that, deep down, Thanos wanted to kill half of all life so he could say “I told you so.”"
