IMO this man's case Is different and I won't blame any addiction for such low thinking, how would he kidnap his own granddaughter to get ransome to gamble that's the most absurd ive heard of.
Addiction can most times push people to the lowest of character and often make them do the most insane things especially when they let the addiction do the thinking for them. I usually thought drug addiction was the worst but now I know all addiction are the same.
