Super Freak
Right so he gives up the entire plot of the movie because his most hated nemesis has his mothers last name, then promises to save her, then calls his enemy my friend literally 5 minutes later. Yes that makes perfect sense. And why did superman even choose to fight batman? Because Luthor blackmailed him - superman... by kidnapping his mom which batman were able to locate in a few minutes? Perfect sense.
If they wanted to do batman vs superman then go all injustice, then at least the storyline will make sense. Not because supermans mom got kidnapped...
As far as their animosity goes, that's pretty self-explanatory. Batman views Superman as such a danger to the point that he dehumanizes him and considers him a monster come down from the sky who could rain down death and destruction on every living thing. Superman believes that Batman is a mad man who has turned Gotham into his own police state with his terrifying persona and one-man war on crime. As far as their final confrontation goes, though, Superman didn't want to fight Batman to the death.
Luthor gave him the ultimatum, yes, but he explicitly tells Lois that either he can convince Batman to help him, or he'd have to fight him. Batman didn't really give him the chance to explain himself, initially, bombarding him with machine gun fire, super-sonics, and Kryptonite gas, but, even then, Superman continues to try to get through to him as the fight goes along. Ultimately, I feel like the "Martha" thing shocked Bruce, naturally, but that Clark's pleas for help were what made him realize that "yes, this is just a guy. Same as anyone else."
