On a fishing trip when we were younger he thought it was funny to stab and decapitate the fish and stick the heads on sticks that were then put into the ground. I thought it was weird but was too young to know it was wrong and disturbing and as someone who grew up in a family that hunts blood and guts were nothing new.
The guy straight up admitted to me during a drunken ramble he wanted to kill a lot of people and he emphasized "a lot"
He bragged about how he was cut off in traffic and then chased a guy with his arm flaying a machete out the window.
Loved to talk about stabbing things. Like people he hates or animals that are useless to him.
I don't talk to this guy as much anymore. Still see him once in a while and tell him my life is really too busy to hang out. Recently he asked me if I wanted to go on a hunting trip. I quickly and politely said no thanks I am a vegan (lies) now. He looked at me with a face of disgust and said you've changed man and then suddenly reminisced about the time we went fishing and he decapitated the fish.
