Why do people hate on other people and go talk about them behind they back

People can hate others for many reasons, jealousy is the usual cause of most hate from individuals and or groups in most cases. Others just crave the attention from others, and because they are unhappy with something in there own life and putting others down somehow makes them feel better which is never ok.

People do this people are too afraid to show emotion to each other and are too suborn to deal with the problem face to face. In other word people hate on each other to mask or hid their own flaws.
