What's Kuzan's deal actually? He seems like a really indecisive one. Outside of hating Akainu and liking Garp I can't really get a grasp on his idealogy.
Like Kizaru is more straightforward, he's a salaryman who likes his little bro and hates pirates, Kuzan is like...respects Garp, thinks Akainu is bad for killing scholars but tried to take out Saul himself?
