Sports are very weird aren't they? There aren't many other places that you could wake up in a bad mood one day and decide "yep, today I'm going to maim someone and cause them potentially lifelong physical problems", and get away without any legal repercussions whatsoever, and only a very temporary slap on the wrist in the sport setting. Reminds me a lot of Palhares blowing out dudes' knees, Aoki breaking that guys arm and gloating about it, etc. Thank goodness most martial artists are honorable and this is the exception, rather than the rule.
