How fast can you think?

Apparently it is such a bad thing to think evil thoughts... well whatever. The point is that you are supposed to stop the thought before it gets any worse. Well what if you think too fast? What if before you can even identify it as a bad thought to stop it, it is over... you have already... destroyed them. You find yourself looking at them in this fast moment... just standing there watching as they wriggle on the floor... nothing except unmistakable pain. There they are, bones broken, face shattered, everything is over for them... they lost to themselves. Not because they lost to you, but because they brought it to themselves.
