The term 'Deadly Sins Number' refers to the SEVEN deadly sins, which are a set of SEVEN vices that have been recognized since early Christian times. These sins are pride, greed, lust, envy, gluttony, wrath, and sloth. They are seen as the root of all other sins and are considered to be particularly destructive to the soul. The number SEVEN is often associated with these sins, as it is believed to represent the full range of human failings.
