You've created your own head canon/filled in the blanks to justify this Superman's character. The films are supposed to do this. Breh barely knew Lois in MoS. When they kissed in front of a burning metropolis, there was zero build up to their romantic relationship. Of course other than: He Superman, she Lois, they kiss.
In BvS the general public liked him, the government didn't. I mean a stature was built in his honor
That holy savior montage where Superman was looking pissed to save people showed how the people world saw him.
Theres a decent Superman character arc hidden in BvS but the creators could give a shyt about that. As soon as Superman was is a platform to actually have a voice and give his opinion, Synder literally blows up the film then kills him. This speaks volumes of where these peoples priorities are.
