Cause and effect in crime

Nature or nurture?
   I see a pattern in many of these events, the apparently predictable and apparently unpredictable.
1 The upset person suffers two (or more) major traumas e.g. own or parent's divorce, moving home, bereavement, loss.
2 Alone/in gangs, they escape from problems into: a drawing, religion or video which portrays a battle and suggests a culprit to blame, a victim, and means of attack.
3 They commit suicide or attack their next of kin or both.
4 Or they attack somebody who they think insults them.
5 Or they attack everybody of the same type as the one they blame (another mother, redhead, Jew, white person, black person, redhead, policeman, teacher, member of football team, race, nation, person wearing a uniform, having the same hairstyle).
6 Or they attack through jealousy somebody who has what they just lost.
7 Or they 'kick the dog" - take it out on the nearest person who has nothing to do with their problem and could be trying to help them, hinder them, in the way, or simply nearby.  

Time For Tea Breaks Twice A Day (or coffee or water - with a biscuit or apple or banana or grapes)

Researchers discovered that you can only go without food and water two hours in armaments factories in war time and introduced the two tea breaks a day for elevenses and tea time. That was the innovation of the tea break - not to be kind to workers but to increase productivity. Food and drink are not luxuries but a necessity, like putting petrol in a car.
