The seven deadly sins -- wrath, greed, sloth, pride, lust, gluttony, and envy -- are really nothing more than a basic description of human nature. All of those sins are committed by everybody, and on a daily basis. The only danger is in letting any one of those basic human instincts gain too much control over your life.
The only really unforgivable sins are:
1. An inability to admit fault.
3. Habitual dishonesty.
Funny how these three truly deadly sins always cluster.
