In mos he did give up his entire race to save humanity. That did happen.
In bvs, he sacrifices himself to save louis, not the world. He fights batman not because their ideologies crash but because he was forced to for his moms safety.
He couldnt care less about batman at that point, he didnt even care about batmans light showing in the sky.
He shows up in africa to save louis again,
The entire theme of this movie is how he only really cares about louis.
He sacrifices against doomsday to save louis "HIS WORLD"
It almost makes sacrificing his entire race in mos pointless. Since all he really cared about was louis.
The entire flash dream was about how louis getting hurt would make him become evil....
Like i said, devolve, he went from caring about humans at the end of mos to only care about one human woman
and the movie actually does show him getting annoyed about saving people.
His mom even tells him no NOT BE NONE OF IT, YOU DONT OWE THE WORLD A THING..
We have a superman that after being superman for a couple of years he is ready to call it quits
The next movie should be called
man of steel 2: Superman rises.
