I hope I'm wrong and I'm just reading too much of the Daily Mail comment section.
But having worked with people with schizophrenia and having had a brother who also had schizophrenia, people just do not understand that when they commit crimes, no matter how violent, that this is the result of severe delusions which affect their ability to think rationally and within normal moral constraints.
They are out of touch with reality and therefore do not have the understanding that what they have done is morally wrong.
My brother was violent and once picked up a brick and threw it at me. He truly believe I was taking his thoughts from his mind and broadcasting them to others. He did not have the understanding that to injure me would be wrong.
When someone is suffering a delusion they do not think in reality.
AIBU to think people still don't understand?
