That was really interesting. It is hard to take anything on face value though, after his past lies.
He took the soft option whenever pushed, being very quick to blame his poor state of mind for his actions. This was such a protracted period of time that i just don't think that he could have been so badly in denial, then just bounce out of it and come clean.
His upbringing sounds bizarre though and obviously taught him to lie from a young age.
I am intrigued.
