In a recent question / answer, it was asked "how can a person know that an action is immoral, yet do it anyway?" and the response was "a person can 'know' things on different levels and so can engage in self-deception." I have a question about the response, which then leads to a deeper more qeneral question. Suppose a person knows that an action is immoral, yet does it anyway. Might that not indicate that the person [at least in this instance] does not care whether s/he behaves in a moral manner? and where does the concept of 'evil' stand in philosophy, and how might the concept of 'evil' explain this apparent disparity?
