Yes. While being a compassionate person who generally does not want to see others hurt or suffering, I have a deep love for violence. If only violence could be done without anyone getting hurt. Perhaps some leftovers of a human predtory instinct...
I myself engage in various martial arts but generally keep sparring to a minumum (I know, this is not conductive to becoming an excellent fighter). Too many head injuries frighten me as my mind is very important to me. However, I have done some serious sparring a small number of times because the experience is absolutely essential. KOs suck. But practicing techniques and doing padwork is excellent. The feeling of impact and transfer of force is a lot of fun, plus I get to learn a powerful new skill.
