When it comes to commandments I've broken 1, 3 4 and as a divorcee I've broken 7.Well it is hard to confess to something that requires a deity to judge your actions.
But adding knowledge/experience or anecdotes to help others in financial need would generally be the opposite of greed.
Well none of that is greed unless you intend to acquire it by unfair means or at the expense of others.
5, 8 and 10 are open to question.
And 6, yea I forgot about that.
Well that's a different sin altogether, that's envy
The Greeks had the 7 deadly sins. The Christians actually had 8 so talking about the 7 deadly sins is probably a sin. When you die John the Ascetic will kick the backside off you, though some pope did change it back to 7 so maybe you'll be alright.
Edit: It was Pope Gregory (who else I hear you say).
