The categorical imperative, in this case, is simply a slippery slope argument. Something people overlook is that the slippery slope fallacy is only a fallacy in a logical context. People aren't uniformly logical entities, and slippery-slope arguments are not always fallacious when applied to human actions. At some point in any analysis of human behavior and ethics, philosophy is no longer the right tool for the job. You have to turn to psychology.
