A statement of the obvious: psychopathy and human rights abuses

Sometimes the statement of what is obvious can seem quite annoying; however, doing that - stating the obvious - can also be essential in not placing undue reliance on verbal contracts - such as political "conventions" - that can be ignored, as POTUS45 has shown in the USA. 

The naivete of some advocates towards school bullies is one area I've long held concern over. An area that has gained attention of the zeitgeist is that animal-abusing children MAY grow up to become mass murderers, which - from memory - is based on a simplistic and unnuanced view of a US study. Another matter is the possible role of psychopathy in soldiering - I've read a fair bit (especially in Paul K Chappell's books) about the difficulties military have getting people to kill other people, with some finding as few as 25% fired their weapons to kill in World War (part) Two, another alleging only 2% of the soldiers in some British army units were responsible for all the killing, and so on.

And now we have a study suggesting psychopathy has a role to play in human rights violations. 

Yes, it may seem to be a statement of the bleedin' obvious, but, as this is evidence-based and reasonably objective, it also raises the prospect of being able to identify and better manage the risks of such abuses BEFORE they occur.
