[DC] What would Superman do if a time traveller showed up with proof that a kid he's going to save from an accident tomorrow grows up to kill millions?

Bonus round: how about Batman or other heroes? Are there any who would definitely not intervene and let the kid die?

He'd still save them. They're not really consequentialists, none of the main DC heroes, at least most of the time. They do things because it's the right thing to do. Letting a child to die is just abhorrent to them, no matter what he/she grows up to do.

Plus, the future's not really set on these things, for all they know, it could be that they have this knowledge and how that makes them act that makes said kid grow up to kill millions. Maybe they'd monitor the child, but potentially anyone could go on to murder millions, so it'd be weird to just focus on one kid.
