Lust-Envy-Pride Party
Wrath-Avarice-Gluttony Party
Are you suggesting that both parties are Slothful or that both are Diligent or that both parties seem to be both at all the worst times?
I could see a good argument for either being the Party of Sloth, so I just left it at 3 for each.
Well I guess you could include Despair (the 8th deadly sin) if you want to round them out.
Despair is a special form of pride, in that it is fundamentally the belief that the people and things of the world are somehow so great as to be able to sin beyond God's capacity to make things well.
