I would go in with the best intentions of fixing the world, but probably eventually end up disillusioned in the watchmen plot, because people are just so shitty and the only thing that can make humans play nice is an external threat.

Fuck no, stop the wealthy, threaten anyone attempting to wage wars, genociding, opressing.

Distribute resources, build schools, destroy datacenters.

I mean, as always it depends on which Superman we're talking about. I've seen some depictions that treat the super-hearing more like a curse. Could you maintain your apathy if you could hear every pained scream and every cry for help in your city?

Not to mention, some depictions have him on the level of a god where you certainly could do whatever the hell you wanted, whereas others have him a lot weaker and closer to something that the world could defeat if he really became a problem. I don't think I'd want to take on the world if I knew a nuclear arsenal could still take me out.

Idk man, you have the capacity to do whatever. We just assume a nice guy narrative because that’s what we’ve come to expect.

If some random human was superman, they’d just kill all the bad people. In my case, until utopia existed. And then any bad people who challenged that utopia. Because whats the point of ultimate power if you never use it for good?

And sure, bad guys will pop up to cause problems, but they do that anyway. Musk, bezos, pick your poison, they crop up all the time and need to be stamped down.

You as superman stomp those all down. Fatally. End-of.
