I don't really think there is a reason to hate Kikyou, sure, she attempted to drag Inuyasha to Hell with her, and tried to kill Kagome, but who could blame her? Naraku tricked her into thinking Inuyasha killed her (the one who she loves and trusts), and to come back from the dead to see her with another girl. You need to finish the anime series, and the Final Act, Kikyou accepts Kagome, and lets Inuyasha lead his own life, now she watches over them. Protecting Kohaku's light..
I mean, Kikyo is basicly a zombie living off of the souls of the dead, and having to see her lover be with another women in this time. I feel sorry for her. But that doesn't mean that she can go after her lover to kill him, even if she was deceived by Naraku into thinking Inuyasha killed her, she knows that now so why keep trying to kill him. Let him get on with his life Kikyo, you had your chance.
