I’ve always had this theory in mind that people who talk behind people’s backs destructively are unhappy, miserable, jealous, insecure people. They wanted to do things which they can’t and it frustrates them, hence, they resort to backbiting. Also, they are cowards as they aren’t brave enough to face their insecurities and confront their real enemies – who are themselves.
Or could it be just plain boredom? Being not busy; having lots of idle time on hand can make a person nosy. I’d rather mind my own business or find something productive when killing time. It’s better than sinning. God bless all miserable people. Glad am not one of them. 🙂
