Why I hate Ereri

He doesnt partically cares

I'm not saying that Levi HATES Eren I'm saying I don't think he is that important to him.He even beat the crap out of him to show that he was weak.Levi understands that Eren is a monster.Although Levi later accepts Eren and saves his life that doesn't mean he likes him.It was his job to save Eren.If he was given the choice
to save Eren do you think he well do it? I don't.
