People can use a car to act out their suicidal urges and drive at high speed into a solid object. This is then an expression of suicidal urges. However there are others who will drive such that their own and others lives are put at risk and some times people are killed. This is different as it is an expression of homicidal – suicidal urges.
Even in death, suicide and murder there is still a childlike innocence, because they are still childlike thinkers to some degree.
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.
Is there any difference in the self destructive motivations of these two men?
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.
