It's called being hypocritical. Or two-faced. Or phony/fake. Some folks are very good at it. Practice makes perfect as we all know. Human beings. Disappointing at best and reprehensibly evil at worst. Sure there are a few very good ones who stand out and are lauded. But mostly humans are a sorry lot. They know better and could do better but they just don't give a dam*! :( SIGH
