Yamamoto has a big sense of honor and justice, he's the kind of guy that would rather die than do something he consider dishonorable. Yet justice is relative and probably because of that the two of them clashed in the past.
Yamamoto's justice seem to be centered around power; the strongest is justice, the winner is justice and the powerless should obey the strong ones.
Justice is moral rightfulness. Forcing the weak to submit to you, and conform to your ideals/rules because you are the most powerful, isn't noble or just. Neither is using a person's dead comrades as a meat shield to affect your opponent emotionally and psycologically. Yama-ji is a lot of things, but noble and righteous...I'm not so sure. Kubo wants us to support the Shinigami, but that doesn't mean the Shinigami are inerrently good people or right all the time.
As for those complaining about "haters," you must have a limited view of what it means to be a fan. Being a fan doesn't mean you have to like every chapter and every idea that the author has. It doesn't mean you have to like all the characters, or all the arcs, or all the dialogue. There are entire arcs of One Piece that I utterly despise, but that didn't stop me from giving the manga a 9 overall.
A forum is about discussion and an exchange of ideas and thoughts. If you can't handle people having a negative opinion about an aspect that you like, forums are not the best place for you. Even if a person states that they dislike a core part of the manga, they aren't required to write an essay justifying their feelings, nor their descision to keep reading. Everyone's opinion is legitmate.
