Akainu is horrible
Kizaru doesn't care either and I'm assuming Greenbull will not be any different.
None of that is them doing anything to you though.
Also, that leaves Fujitora and Aokiji, who are the best.
We literally know nothing about Greenbull.
Kizaru is just mysterious but he clearly cares in some way or he would never have become an Admiral, a position that requires dedication.
Akainu’s decisions, even if morally unpalatable, are driven by logic and practicality along with a belief that what he is doing is genuinely necessary which is far more than can be said of Garp, an individual that dislikes things but carries on because his job is cushy.
As for my dislike of Oden, that has to do with him swinging from Gary Stu to utterly useless faster than you can say “street dancing clown”, an utterly boring backstory, everyone loving him despite his utter mediocrity, his utter failure to even try to save Wano when it was actually achievable and the second worst introduction to a protagonist character (using a man’s cremation pyre to cook food) that I have seen since my eyes bled from reading Afro Samurai.
