That's becasue he loves her.
So it's his problems as I originally stated.
Well, duh, it was his responsibility. He loves Lois.
Superman's responsibilities don't include to love Lois or defend her especially over the rest of humankind.
It's really simple, you do special things for other people b/c you care more about them than anyone esle.
Except if you're Superman and you have a bigger duty to do your best for everyone, not just the ones he personally loves.
But that does not mean you turn right around and hurt them the next day.
Yes it means that, if your bigger duties interfere with your girl.
Like when Clark had to regain his powers and explain Lois they couldn't be together and now it was definitive. He hurt her (even if later he deleted that memory from her mind, the fact remains) literally the day after.
Like when Supeman had to go to Krypton and didn't want to risk his mission by surrender to his own temptations, namenly Lois. He hurt her.
I know you don't get S:TM and SII.
Bare statement.
It is supposed to be that way just because you say so
I know you think that Superman is just some guy whose selfishness gets in the way of his altruistic mission,
I think it because it's the way it has been in the movies.
but that is not what the character or S:TM and SII are about.
To allow a missile to potentially kill people in STM but to reverse time just because his precious Lois was dead - even when he knew it was wrong - is selfish. And if you don't think it was wrong, just trust filmmakers' sugary intentions showing us how Jor-El was his mentor and father and told him specifically to not to do it.
To quit his mission and let any villiain or any danger to kill people because he had to get the girl is selfish. To go back to a restaurant and use your super-powers over a human being because of personal anger is utterly selfish.
I know the world is a different place today than in 1978 and people are much more jaded and untrusting of others who appear to be genuinely good. But SUperman is not like that, he REALLY is that good.
He wasn't that unlselfish back in this franchise. He has been selfish, he has made mistakes.
1978 or people who pretend to be good and they're not have nothing to do with that fact.
And if you don't get that, you don't get Superman. And if you don't get that genuinely good and honest people don't ditch the woman they love for 5 years w/o a goodbye, you just don't get what a genuinely good and honest person is.
Donner and Lester didn't get it then.
They allowed Superman to put Lois' lives over others', they allowed him to quit his mission for personal satisfactions and they allowed him to manipulate minds just because he decided to. They allowed him to have a personal revenge abusing of his super powers over a simple human.
That doesn't match a genuinely good person.
For the last time: It's not better to be dead
That rule is for everyone on Earth, not just Lois. he does it just for Lois.
and it's more of a burden on Superman to erase Lois's memory than let her go around in emotional distress for the rest of her life.
No one has been in emotional distress over a broken relationship. Every human being has lived that and it's part of life. Once again, for his own satisfaction, Superman was changing human history.
The only burden he'd carry is that he was not man enough to ask Lois first if she agreed about having her memories deleted. It's the least he could have done IF he really loved her. You don't decide the other person's fate by yourself if you truly love. You don't take people's things and right away without a warning just because you thought it was ok if you truly love.
He realizes he made a mistake and that b/c of that it is not fair to Lois to be dead
What was the mistake in saving other people?
By using his time to save only Lois he was risking more people to die. He was where people needed him more. It was not a mistake, it was just that Superman didn't like how things turned out and decided to re-write history for his personal satisfaction.
or in emotional distress,
THAT was a mistake and as a mistake - as any man having his trousers properly on - he should have assumed it and not tried to delete it AS if it never happens.
Lois has the right to know who she has been intimately in bed with. Superman took it away.
In SR, after he made a big mistake, Superman didn't go and erased history in any way, for his own satisfaction. If this was Donner's, Superman would have reversed history so he never had a child with Lois so the poor girl wouldn't die of distress. And in the way, he would stand as a true hero only because people and/or Lois weren't allowed to actually know what Superman did wrong.
therefore, he uses his powers to the ultimate degree to right those wrongs
Exactly. He doesn't use his powers to the ultimate degree to stop the missile and save all the poeple. He uses his powers to the ultimate degree only to correct his mistakes, not for the good of all people.
and give LOis a chance at a happy norman life while still being alive and not a corpse.
Breaking up a relationship hasn't killed anyone in a normal mental state. And if he wants to bring people to life as part of his mission he's more than welcome. But if he does it for everybody.
It's really not that hard to get. Superman has no ulterior motives,
As you have said yourself, he has them. Lois' life and his relationship with her being it. That's behind him reversing time, quitting his mission and manipulating minds. Not the good of humankind.
And his personal anger carried him to fight back a human being just because he humilliated him first.
he's not a skeletons in the closet guy.
Time reversing, mind manipulation, killing Zod, personal revenge out of anger. Being Zod the most literal skeleton of them all.
He's straigtforward good, caring and honest. I know it's tough to find some of these people these days, but that's who Superman is and that's his motivation. That's what S:TM and SII capture and what SR fails to capture, it is that essence of Superman.
As I've said mentioning the facts in the movies, not merely making statements; it is not that way. Superman in STM, SII and SR are the same. And I might add some things Superman did far less selfishly in SR than in the previous 2 mentioned movies.
