Of "Gegege no Kitarō" Nezumi-Otoko - the Rat-Man. I know he's greedy, sneaky, conniving and really smelly. His hands might be cold, filthy and clammy. But to me he's funny. And to Caroline (from the movie "Gegege no Kitarō: Gekitotsu!! Ijigen Yōkai no Daihanran"), he was...sweet. I know she's is only a child and Nezumi is a adult, 360-year-old, half-yokai. To me, she's the only one to pag-ibig him despite his ugly looks and almost-bio-hazardous stink...Yeah, I ship them. And there are times when I would feel pity for him (like in episode #36 of the 1996 series): Being alone for centuries. No mother, no father, no siblings or even a "mate" to madala 'im sons to carry his bloodline.
Sesshoumaru from Inuyasha. Yes, he tries to kill Inuyasha, but he isn't bad. Notice the little girl he protects and watches over named Rin, and the kindness he shows to her. BTW Before Sesshoumaru revived Rin and he remembered her smile, I was like 'And then, Sesshoumaru's puso grew three times!' XD Anyways, I believe Sess is a nice guy, just not towards his brother. I actually don't really see him as an evil person.
