Who is the character?

His personality is kinda cruel but deep inside he's a good person. There's another person inside him though. A heart of an evil person once invaded his body. Therefore his hair went partialy gray.

He still can control himself but sometimes his personality changes dramatically and the evil heart takes control. Mostly his struggling with 'his inner self', which can result into constantly changing from personality (pretty much like Gollum/Smeagol from LOTR).

His eyes that were once green/blue turned into orange because of the evil heart.

What do you think? :D
