The seven deadly sins are a classification of 'vices' that were originally used in early Christian teachings. They are sin, lust, greed, wrath, gluttony, pride, envy and sloth. They of course now have a place in popular culture miles away from their Christian routes.
I really like the tattoo with the body mod corset as all the sins are in different fonts which are matched to the sins.
Naturally most of these are typographic, which are my favorite type of tattoo because the image will always look perfect. For what is it worth, I also think the checklist makes this awesome idea a bit rubbish.
