HEROES star Masi Oka has stopped behaving badly because he can't stomach the idea of hurting people. The Asian actor admits he took his fame too far when he first became a star - and he blames co-star Milo Ventimiglia for trying to lead him astray. He says, "Milo was single and telling me, 'You're f**king Masi Oka! Live it up!' "I actually did for a bit, but I don't like hurting people. My mom raised me to be a gentleman."
