For a secret assassination, the contrived accident is the most effective technique.
When I played pro football, I never set out to hurt anyone deliberately - unless it was, you know, important, like a league game or something.
I was shot in the wrist when I was a kid. Deliberately.
I never paid, or intended to pay, $10,000, or any amount of money, to any player for knocking Kurt Warner, Brett Favre or any other player out of the 2009 Divisional playoff game, 2010 NFC Championship Game or any other game.
There is an essential difference between someone who harms a child on purpose and someone who harms a child by accident during combat in civilian territory.
I've seen elbows that broke eye sockets. I've seen a German goalkeeper just level a French guy. His teammates thought he was dead lying on the ground. This was in 1982 at my first World Cup. But a bite is outside any kind of contact collision: dirty foul play. A bite is a bite.
A long time ago, I had a bird that annoyed me, and the bird had to go. The bird's neck was snapped. I would also snap Conor McGregor's neck in a similar fashion.
I never set out to intentionally hurt any player and never enticed any teammate to intentionally hurt another player. I also never put any money into a bounty pool or helped to create a bounty pool intended to pay out money for injuring other players.
Harm seek, harm find.
