Even in case (4), even if abortion kills what is not in fact a person, but the killer does not know for sure that it is not a person, we have criminal negligence, as in the above three cases if there happened to be no man in the coat, the bush, or the building but the driver, the hunter, or the fumigator did not know that, and nevertheless drove, shot or fumigated. Such negligence is instinctively and universally condemned by all reasonable individuals and societies as personally immoral and socially criminal; and cases (2) and (3), murder and manslaughter, are of course condemned even more strongly. We do not argue politely over whether such behavior is right or wrong. We wholeheartedly condemn it, even when we do not know whether there is a person there, because the killer did not know that a person was not there. Why do we not do the same with abortion?
