Throughout phases 3-4 of the MCU, Thanos tries to, and succeeds in wiping out half of all existence.
He says this is due to overpopulation (a different motive from the comics), but Eternals tells us it was to stop The Emergence happening on Earth.
So, my 2-part question:
- Why did he lie about his true reasoning?
- Why did he eradicate all life, and not just Earth's?
