Interestingly enough I like Kizaru a lot. He is not a bad guy, so far, we haven't seen him being corrupt or something, he is just like Akainu but way more forgiving than him. He is just doing his job so we don't really have an excuse for hating Kizaru. Can't hate an officer for pursuing criminals.
Hmm, yeah I won’t deny that he hasn’t give any reasons to hate him. But he still protects a justice that is wrong, that’s why I like Smoker and Aokiji.
But the main reason (and kinda immature) was his personality and attitude. It’s irritating at some point?
