Thank you from my heart for your input. I was totally unawre of any study. I am just trying to get a grasp on what makes thes people act as they do.( I don't know if the word act is the right one or not )<quoted text>If you want to study pychos /sociopaths look to Soldiers , you see the bullies.
A study had been done (Forgot name of research group) on Pyscopaths/sociopaths represent 5% of the US Population the group includes most Soldiers, Corrupted leaders, presidents/Dictators, Murderers, Killers, violent offenders, Bullies... are causer of society problems at home and around the world. If you get rid or these or put them in jail you have fewer problems in society.
