Now I'm talking about Hate, not love.
I hated Danzo so much for some unknown reason, the way he talked was so annoying. I respect other opinions so I bet many of you will say Kaguya.
Danzo: made the villagers distrust the Uchihas by not allowing them to help when Kurama was attacking the village which also built suspicion of the Uchihas. Took Shusui's eye when he wanted to use it to try and stop the coup. Order the massacre to Itachi after he made it the only solution. Was the benefactor for Orochimaru's experiments. Madara Hanzo distrust and attack Nagato/Yahiko/Konan which made Nagato a bad guy. Didn't help when Orochimaru attacked Konoha. Didn't have when Nagato attacked Konoha. Tried to manipulate the Kages and could have made things worst for the village if the Kages wanted to attack.
I see why you hate Danzo^. I dislike Obito, Madara, and Kaguya for about the same reason, they all had/have enormous power and show be using jutsus like lava, jinton, boiling, ice, magnet, ect... Madara used storm element only and that's all, no fire or wood jutsus which he used as Edo tensei and when he was revived nor did he use Susanoo as Juubi jin when he did blind and with 1 eye before he was juubi jin. IF BZ is combined with Kaguya then he should have uploaded all the fights he recorded over time, which was all akatsuki fights, and have her use jutsus from those fights but on a higher level? Kishi could have done the manga a lot better by making the villains do what they are capable of doing but he just rushed things.
