"Beware the man that has nothing to lose, for he has nothing to protect," he captioned the note.
"Over the course of the last week, through introspection that should have happened many years ago, I have come to some stark revelations about my character. It is a testament to my utter ignorance that these revelations had not come sooner. 'You see, I believed myself to be a good guy. I have not been a good guy. In fact, I have been a pretty bad guy throughout my life."
"I hope that the people of the world can utilize my folly in a positive light. That you all may use my mistakes as an example for personal growth. The lesson has come too late for me, but perhaps it can inspire you," he said.
