Psycho - Vance Hopper

Vance Hopper - A 'so-called' psychotic son of a bitch, everyone fears him; his friends, his enemies and even the authorities.
His hard shell pushes everyone away, and he isn't afraid to act on his awful demeanour. There couldn't be a single person who would even have a chance at seeping through into his 'stone cold' heart.
Or could there?
