It's the same premise basically. He cares about a nonsensical perfect world which no one in real life believes in.
"You were chosen to be a movie star, correct? Isn't it your duty to be ever beautiful? Everything beautiful should stay that way forever. I would make this world unchanging and eternal so all beauty will last forever.X/I would end the world in an instant so that beauty never fades.Y I can't stand the thought of the world becoming uglier."
It's the BEAUTY that's his motivation for cleansing the world of bad people. It's all about that notion of beauty.
"When there is only one of something, it can't be shared. When something can't be shared, it will be fought over. And when something is fought over, some must survive without it. The only way to create a world where people live in beauty, a world without conflict or theft, is to reduce the number of living things."
There's also a hint of Thanos-level "overpopulation but not enough resources" motivation too.
