Evil? Nah.. Fix the fucking planet, man.
All plastic in oceans? You just see a giant ball of mess just collect and float upwards. Where it goes? Haven’t decided yet.
Rainforest? You start seeing trees sprout, grow, and come back to life, replacing and replenishing the burnt land.
Oil spills? You see black slowly become blue as the oil is then pushed back into the earth, then resealed to not leak.
Hell, you play God and fix things, you either get praised or start getting hunted down. Course, by then, I would’ve made myself immortal. The best they could try to do is lock me up.
