Mmmm, there should be a sort of mix of attributes to render the characters interesting, so it doesn't end like a wicked adaptation of the seven dwarves where all of them are just exaggerated versions of the ideas they embody.
Therefore, the main attributes on the characters should be something to make the characters active and clash between one another. Lazyness, Gluttony, Ignorance are fine sins for humanity, but I doubt some interesting characters can be made from those unless they have something more.
By the contrary, arrogance, narcissism, apathy, bigotry, racism, etc, are sins that end in active characters. If you ask my opinion, cruelty and sadism are the worst of them, because suffering becomes the goal of their actions, instead of just a consequence.
