I honestly think that he is trying to avenge his mother's death somehow. He can't accept why it happened and move on. He's consumed with hatred, it's unhealthy and it's misplaced. Those tragic events happened nearly 30 years ago.
He should remember the saying that hatred is like drinking poison and waiting for the other person to die. IMO he needs proper help to have any chance of ever finding any sort of peace - but he also needs to grow up and accept responsibility for his mistakes. Maybe it's too late for either, sadly.
Playing the victim
ad infinitum/ad nauseam will do nothing to help him in the long run; and the irony is he's using compliant journalists to spread his distorted propaganda. Presumably the person who interviewed him for TV doesn't qualify as a "baddie" because she is doing exactly what he wants; but he is using her, and the media for his own ends when it suits him, nevertheless.
As I said before, if he seriously believes what he is saying, then he is delusional and/or under the influence - of something and/or someone. IMO he's been conditioned, programmed, brainwashed - pick your adjective. And the further he goes down this road, the harder it's going to be for him to ever come back from it.
And on that note I will go into lurk mode for the rest of the evening, I have a little cat who needs me and I need my dinner! Have a good evening everyone
