Why is it that Son of Sam wanted to kill seven people?

Answer 1

he had a schyzophrenic disorder and claimed his neighbor's dog was possessed by the devil and told him to do the killings.

David Berkowitz was diagnosed as having APD with possible narcassistic personality traits. In a recent interview Berkowitz admitted that he had made up the dog story. If you look at any of the news film clips of Berkowitz after his arrest and he looks like a man that is very pleased with himself. That fits right in with his personality disorder.

He claims now to have found God in prison and I hope he's right. I'm always amazed at how many criminals find God in prison. He must hang out there alot.

Answer 2

More than a decade after SOS killer David Berkowitz's multilple murder sentences investigative reporter Maury Terry discovered the real reason behind the SOS killings. Berkowitz had claimed all along that 'the devil made him do it', and he was in part, right. Berkowitz belonged to a Satanic cult known as The Process. The murders were a result of this cult's Satanic sacrifices, many of them on or near dates of Satanic holidays.

It is also probably true that Berkowitz himself did not kill all of the New York victims. He said he was responsible for only three, the killings that occured in the Bronx. This would explain why the composite drawings from eyewitnesses gave such different descriptions. The Process is one of many different branches of basically the same Satanic cult that probably originated in the UK during the 19th century by renowned Satanist Alistair Crowley.
