He says in here that every murderer he knew in prison had a history with pornography without exception.
Probably 95% of men have a history with pornography, and that's a very moderate estimate. Not that I'm excusing it or saying that anyone should watch it, of course, but in a time where the Church is under attack and the world has apostasized, people are slaves to whatever the devil wants to do with them.
It is true that pornography breeds a desire to see more and more salacious things. To say that it will drive people to become Charles Manson, well, it's possible though it would be uncommon. I'd say more often it just leads to dehumanization and a spiritual estrangement between the sexes. Pornography will give you a very diseased view of women. It can lead to a sort of gnawing sɛҳuąƖ jealousy that can certainly lead to murder if someone is so inclined, in the same way as adultery, or even immodest dress ( like when you hear about a murderer who killed a girl because she was teasing men or whatever ).
I wonder how many women know just how fragile the male ego is or how much they play with fire when they tease and play around with certain men.
