re: Is someone a good man if they derive pleasure from people thinking they are a good man?

If someone is doing good deeds solely so others will think he's a good man, then he's being a bit duplicitous if he's allowing people to think he's doing good deeds simply for the sake of altruism.

It doesn't necessarily make him bad, just not good to the level of being virtuous. A person who does so suffers from hubris.
