I appreciate that you ' ve put a good amount of thought into this , but I ' ve gotta disagree . Sesshomaru had some hate for humans . But I think that ' s an attribute of most demons . Demons are simply above humans in a demons eyes . Sesshy boy just didn ' t go around picking fights with what he considers insects unless they were a nuisance . That was practically the entire point of the Rin storyline . He grew to see a human as something other than dirt beneath his claws for the first time . And of course he hated Inuyasha for being a half breed . His great demon father went and had a kid with what they normally see as nothing , and then Sesshomaru realizes his father left his fang to Inuyasha which obviously doesn ' t help . I guess we can speculate any number of reasons that Sesshomaru may have hated Inuyasha that weren ' t shown in the show but what we ' re given is that he hatedor at least thought lesser of humans like most demons . It ' s only natural he would hate his half human brother who ended up being the favored son .
