We all know that people who abuse animals are more likely to be violent and abusive later in life, and we have all heard that the FBI uses animal violence in the past as a way to profile violent/serial killers.
So my question is this: Are there any studies comparing violence/serial killers in high meat eating/slaughtering societies vs. those societies that abstain? I do understand that there is no society that is completely animal product free, but am thinking of those that eat much less.
I just wonder if there is a correlation between these things, and if there are any official papers on the effect of eating meat on violence in general in society. I guess another example would be whether or not a rise in meat consumption and slaughterhouses has correlated with the rise in human violence.
