The man’s an idiot.
Only a complete moron would announce his intentions ahead of time.
I’m not sure you understand this man. He’s going to murder the scum who killed his boy and he doesn’t give a wit who knows it. You would have to be in his shoes to understand the pain and rage he is holding inside.
I have often said that if anyone murders my son he better spend the rest of his life looking behind. Once you loose everything you care about there is nothing left inside you except emptiness and hate. It eats at you like a cancer. I bet the only thing that will cure his feelings are to dispatch the SOB that killed his son. I know I would want to.
