We didn't really get to know Ashitare very well. He only lasted a few episodes. All we really know about him is that Nakago found him and took him in. He has been abused by Nakago ever sense. No wonder he is so violent. You never know. If he was treated kindly maybee he could have turned out to be a poet.
Sadly to say no one fell in love with Ashitare, the unloved werewolf.
