Why does sesshomaru hate naraku?

Answer 1

Sesshomaru's main reason for going after Naraku was that he was angry he had tricked him by giving him a human arm with a shard in it that was rigged to burn him alive, but then the reasons grew from Naraku kidnapping Rin, trying to absorb him, and mostly becuase he talks down to him as if he's stupid (which is the biggest ager indusing thing to Sesshomaru next to comparing him to Inuyasha).

Basically he is trying to kill Naraku for trying to screw him over when they "allied" in one of the earlier episodes

Answer 2

Who told you he liked humans? He likes neither. Rin seems to be an exception and she has begun to warm him up to humans and later on he seems to except Inuyasha... But he doesn't really like either species.

Answer 3

I think personally because inuyasha's mother was a human and inuyasha's and shesshomaru's father died saving inuyasha's mother.
