Lopez had a very strict Catholic upbringing. The rigidity came in the form of a strict observance and adherence as we can assume JP also experienced. From what has been reported and his target being "sinners".
Never heard of that. I know who he is. I have read that repression can intensify mental illness and/or personality disorders.
Broderick and Whitman had very strict Catholic upbringing. Bin Laden, Haigh, Holmes, and Fish came from some extreme fundamentalist background. I get that impression with Drew and Smith. They are severely repressed.
There should always be boundaries and rules, but if someone gets too carried away, it becomes authoritarian. Permissiveness is not any better and just as bad as they feel they can do anything they want.
