My tattooist was raised as a Mennonite and we end up having awesome conversations while she tortures me about her childhood and religion. I floated an idea by her when I was getting my last tattoo done for a sleeve. I wanted to make a demon personification of all the 7 deadly sins and have them all interact kind of like da Vinci's "The Last Supper". So maybe have lust groping greed while envy stares on. Or maybe have wrath attacking gluttony while sloth does nothing. I am still thinking of how to have each of these sins interact and their general look ought to be.
That said, the 7 deadly sins sounds more like a good party than something to be avoided.
