Criticisim of kants morality theory?

Kant doesn't believe that the consequences of an action matter at all – only the intentions count. In a Kantian system, a drunk driver and a drunk driver who hits and kills someone would be punished equally. Kant also has a very strict definition of what it means to act with good intentions – it means to follow the categorical imperative that Kant postulates.

A good example of where Kant offers a counter-intuitive answer is in the Ax Murderer scenario. If an ax murderer came to your door, and inquired where a friend of yours was so that he might kill your friend, Kant says that while you can make every effort to help your friend, you must not lie to the murderer. There are ways to get around it, but it's a good place to start with a criticism of Kant.
