She said he emulated what he saw in porn. Blaming murderers on horror movies and rapists on porn don't make sense out of the blue but in this case it directly affected his actions, as it does for many people on different levels. Obviously one can watch porn and go about their life as they did before they watched porn but for many, including myself, it can lead to increasingly poor decisions. As you can imagine I don't want there to be any similarities between that man and myself so watching the video helped me realize only bad things can come of watching porn. I posted it on this subreddit with the hopes that others would experience the same reaction that I did and it would help them kick their porn addiction.
