I don't really hate any fictional character, bit I get what you're going at!
I liked Kabuto back in Part I and early Part II (Prior to Orochimaru dying). Back then it felt like Kabuto, while following Orochimaru, had a tiny side agenda for his own persoanal enjoyment like when he went James Bond against Kakashi...felt like it was a twisted friendship amongst the two....
Orochimaru being like bet you won't kill Sasuke....Kabuto goes and gets to the finsl point and then backs down simply because killing Sasuke would've been a bad idea XD.
But once he got all full of himself for eating some Exotic Snake and the rest of the sound 4 I was dissapointed...hoping Izanami helps him out with a reality check
