answer:The dictionary defines sin as “an immoral act considered to be a transgression against divine law.” So, I guess it depends on one’s moral code and/or one’s chosen god. The Catholics have developed a rather intricate definition of sin, as defined in the Catechism, Article Eight, Part I, paragraphs 1849—1851, and the types of sin are described in Article Eight, Parts III & IV. It appears that every major religion on earth has a concept of sin, including the Buddhists: “Buddhism does not recognize the idea behind sin, but believes in the principle of karma, whereby suffering is the inevitable consequence of greed, anger, and delusion (known as the Three poisons).” The Three Poisons sound an awful lot like the Deadly Sins to me. This Wikipedia article covers the concept of sin in the other major religions.
