But still, agree that if Anakin had listened to Yoda's advice, Padme would be alive, and he would have remained on the side of the light.
By the way, selfishness and, how to put it correctly... um... madness, I guess, well, in general, about the Sith, or rather about their selfishness and desire for omnipotence:
In this same Episode III, remember what Anakin said to Padme when he met her:
It would have been selfish of the Jedi on Tatooine not to take Anakin with them, leaving him to rot as a slave... which is what they were going to do if it weren't for Qui-Gon... They would have used the boy and left, waving goodbye...
And in general, Obi-Wan should have finished off Anakin, even though that's not very Jedi-like.
And in general, Anakin is some kind of... well, I don't know, I don't remember the type, well, in order to save his beloved, what did he do:
He killed a lot of people, including younglings, he went over to the Dark Side, I personally doubt that Padme would have wanted him to do such a thing for her.
In general, you need to listen to the advice of the Jedi.
