If a person's motive for action exceeds the categorical imperative, their action is permissible. One of the major variants of the categorical imperative is the "means/ends" formulation which highlights the Kantian view of humanity, according to which we should not treat other human beings as a means to an end. . In other words, you shouldn't use people to get what you want. In contrast, in utilitarianism, you can use whatever means (act from whatever motive) necessary to achieve an end whose sole purpose is to increase happiness. Thus, it does not matter why a person engaged in a particular action, but only that the end result is an increase in his ability to act.
