The seven deadly sins, also known as the capital vices or cardinal sins, and they have been around since the early christian times, so a long time in other words. Obviously with them being called the '7 deadly sins' there are 7 different topics: pride, greed, gluttony, wrath, envy, lust and sloth. So I have dug out and opened up my not so modern dictionary at find out the meanings of each of these words to help me get a better understanding of them...
