In Australia most males are emotionally constipated. They are conditioned into stereotype behaviour. Such conditioning leads the more gullible males to show emotions only when they are making love, or in other macho pursuits such as football. They find it hard to display affection and, more dangerously, they find it hard to display their hurt. Some men, unable to release their emotional hurt by crying, will end up releasing it through violence.
Anger is considered to be an acceptable human emotion.
These men do not act out of an inherent evil but out of the unbearable suffering of clinging to painful emotions as if it were a permanent condition. They find no other release for their pain. Much news coverage has been given recently to the woman who drove her car, with her two small children in the back, into a river. She alleges that she panicked at the last moment and leaped free while the children were left to drown. Before making judgement, imagine the emotional state she must have been in.
