Playing rugby I broke a guys neck once, he's okay now but not gonna lie, I was so shocked and afraid for the guy. I mean shit, it was a hard game and I tackled him heavily. He didn't take it right (it's hard to describe, he was unbalanced, off footing) and basically ended up at a horrible angle when he hit the ground. I'm a big guy and I was going full tilt...
Just this big mix of factors, he was unconscious and I thought I'd killed him, seriously. Bad feeling went through me then. I visited him in hospital few days later and he was alright, apparently there's no permanent damage either but shit, I could take it in a fight or something but it was just a game, left me really cold.
Outside of that I threw a guy into a fence once and he broke a rib, I've also broken a guy's nose. Both of them definitely deserved it though and I don't feel any remorse but J, the rugby fella...can't imagine what it would be like to have killed him or paralyzed him or something, I mean shit happens but...god.
