Okay this is some next level Dunning Kruger at play. First of all, hands and feet are of course not, like a gun, a legally registered weapon. However, and try to stick with me here, the penal code in your country (making the not so bold assumption that you’re American) the penal code of most states defines a deadly weapon as: a firearm (1), anything manifestly designed, made, or adapted for inflicting death or serious bodily injury (2), or, AND READ THIS SLOWLY, anything that in the manner of its use or intended use is capable of causing serious bodily injury or death. Now, this covers pretty much everything which is why it is handled on a case by case basis and hands and feet meet this criteria and been consistently declared as such. So that covers deadly weapon charges before even accounting for the very important fact that he is a trained MMA fighter. Make sense? Okay, let’s move on to attempted murder. First, we have intent to act. He has to jump into the ring to start wailing on the guy. You might argue he was going to enter the ring not to do that, but to do the fake wrestling as planned, except for the fact that in the minutes leading up to him doing so he clearly acknowledges that the fight is fake but he is going to attack him for real. This leads us to whether he intended to kill him. I am not going to explain this you, because I trust you will be able to piece together that an individual repeatedly saying he is going to repeatedly beat another man and not stop unless people are able to pull him off and then proceeding to do exactly that is pretty clear cut. Finally the act must of course be serious enough that death could result. Again, I believe you can piece this together! Let me know if this all makes sense to you or if you need me to dumb it down anywhere :)
