Idea:
Quan Chi uses his sorcery to put the opponent under his control. Then, he puts his blade in their hand and makes them stab one of their eyes, twisting the blade, going deeper; there are lots of gushing sounds during this process. Anyways, he then proceeds to have them slit their own throat. He releases them from trance as he looks them in the...eye...and laughs at their pain as they hold their throat, blood leaking out like a fountain, and so much gurgling noises it almost makes you sick. And, finally, he pushes them (or kicks them) onto their back. Then they die.
Thank you for your time.
