If you know it's wrong, why do it?

"All human actions have one or more of these seven causes: chance, nature, compulsion, habit, reason, passion, and desire." - Aristotle

Artistotle poses an interesting explanation for why good people sometimes do bad things. Certainly several of those motivations might account for such activity. If, however, we continue to do bad things, do we eventually become bad people? At what point does it stop being human fallibility and become "bad" per se. Is repenting each time enough? Is believing in God enough? How do intent and action differ here, and what role does each play in the status of our eternal souls?
