No wonder.
they got an actor on his 1st or 2nd job after years battling with depression and addictions (plural, coke and psyco-drugs). He had to deal with being a gay idol after the cowboy movie. he spent months reclused alone at his home, his family had to rescue him and get him in shape (mind and body) to look for work again.

When he was coming back to his senses, they gave him a deep nihilistic psycopathic villan part.
He excelled at it, and then killed himself.
