Impossible to say since once you die you can't tell anyone how painful it is. Like the person above stated, it is impossible to tell. But I know about many ways in which some people have died that were painful to them. Such as the following: * Cancer death. * AIDS complications death. * Labor and birth death. * Having your throat sliced (not guillotine but with a knife). * Being beaten to the point of brain trauma and swelling. * Being burned alive. * Heart attack. * Brain tumor. * Stroke.
