The human psyche is no different. When we see violent images we naturally desensitise and after recuperation we come back mentally stronger. It all a matter of degree.
Suicide and the average man
The Don’t exist injunction is different in that it is a belief a child takes on in childhood. The child basically comes to the conclusion that its own death is a viable solution to a problem.
Suicide and self destructiveness
Is there any difference in the self destructive motivations of these two men?
Suicide and depression
This is what we need to be screening for and indeed this is what I did when I worked in prison identifying suicidal and self harming inmates. If one identifies people with this injunction, as I did with many in the prison system, one knows this person is quite capable of suicide at a later time.
