Shizuru and Natsuki from Mai Hime
I'm not sure that this is actually a good example. Most of the evil things that Shizuru does in that series are motivated BY her feelings for Natsuki. It seems more like a case of Love Makes You Evil then a Morality Chain to me, since her feelings for Natsuki are what are causing her to do those things rather then keeping her from them.
