Where does it say that the thief blamed his childhood on the crimes. It clearly states that his mother, not the thief:
"Kim's mother attributed his strange collecting habits and sexual predilections to depression and isolation.
She said the family's demanding Jehovah's Witness faith, which he had eventually repudiated, combined with his Korean heritage to limit his social interaction with others. She said it left him isolated, socially ill-adept and vulnerable."
I just don't see why people waste their time searching for news articles about JW's. In this case an ex-JW because it states that the thief repudiated the faith.
