Virtue?

This past week we discussed virtue as knowledge. Socrates said that when committing virtuous acts one must be able to define why these acts are good. Good actions are not virtuous actions until the he who has committed them can explain why they are good. We also spoke about how one person's definition of good may be different than someone else's. This concept can be applied to Fyodor Dostoevski's Crime and Punishment when the main character convinces himself for a short time period that killing the pawn broker lady would be a virtuous act. He explains many reasons why the world would be better off without her and how she was an evil woman. He justifies stealing her money saying that it could be put to good use rather than donated to a church to ensure her place in heaven, which is simply a self righteous thing to do. He believes that he is doing good and can define the virtue in his actions to a certain degree, therefore his actions... at the time at which he was committing them, must have been virtuous.
