Stop it. Maybe you saved the girl's life from being cut short minutes later. Or maybe some other life a day or week or month later. He was a bomb waiting to go off, and did go off on Ryan's teeth. I feel sorry for Ryan, but I don't feel one iota of sympathy for the thug. Two previous prison stints and you think he wouldn't have earned a third at some point, sooner rather than later? Live a good life, share your best qualities and focus on the positive results of your actions. You probably saved a life that night.
