If Kant is right, it is illogical to be immoral. But suppose you are very good at benefitting yourselves in ways that are immoral. You are a high-up in a crime family, for example, enjoying a life of luxury financed by murder, drugs and prostitution. If you started being moral, you would have to confess your crimes and spend the rest of your life in prison, maybe even face execution, since you have ordered numerous hits on your enemies. According to Kant, the rational thing to do is the right thing to do, which is to go straight and face the law. But, many of us would think that it is an illogical thing to do.
Is Kant right that it is irrational to be unethical?
