No. Possible. Way.
Superman - Kal-El - has a very specialized set of skills. So does Batman - Bruce Wayne. (Originals only here!) Both have trauma. It can be argued that Kal-El must be basically unaware that he lost his whole planet. That had to be a concept learned later, did it not?
Personal history, I was born Caesarean (due to the level of medical "knowledge" at the time - now we would have just waited a couple days). Had some slightly underdeveloped lungs (ergo the "wait a couple days") and was popped into a plastic incubator. Guess what? I got (at least partially) trained as a psychoanalyst, and such traumas create very specific and permanent "psychological" responses. Mine suss out to be a feeling of being a bit different, unattached at times (or certain circumstances, guess that's why I could do trauma nursing), having very specific opinions based on what I observe of human behavior (what with being a bit detached), not particularly approving of such behavior, being realistic about what could be done (even with a full rack of super-powers) and the main feeling of if everybody else gets triaged and basically taken care of then maybe - just maybe - there might be time to deal with taking care of me, 'cause I'm dyin' here. This is what I always related to with Kal-El. Does not matter if the world continues merrily to Hell in a hand-basket, one strives. One does what they can. Most of the time it works. Sometimes it does not, and we have to deal with that and carry the baggage. Anybody who feels a bit "different" or "isolated" or "doesn't get why the other kids pick on me" has been there. And here's Superman, flying with great power and moving mountains, and he's the same as I am when the lights go out and the night creeps in.
Luthor and Brainiac have a fatal flaw: narcissism. They think they are right, but it is only "right" for them. This is why every plan, no matter how grand, falls apart. Picking historical figures for comparison, Luthor is Donald Trump and Brainiac is Karl Marx. They make big noises, some fall in line, but in the end it comes down to ego and hate and fear. The worst you can do to Superman is kill him, and that don't stick.
Are morals relative or absolute?
