I just watched the latest episode of Inuyasha and in this one, Sesshomaru's mother (who is the Guardian to the Gate of Hell) called up a Hell Hound to eat Rin. She knew that she was sending her son to die in Hell but she didn't care. Of course Sessh followed the hound into Hell to save Rin even though he fronted and said that he was just going to kill the Hound.
