Backstabbers

Be thou as chaste as ice, as pure as snow, thou shalt not escape calumny. -- Hamlet (Shakespeare)

No sooner have you turned your back that they indulge in calumny. Someone leaves them and they immediately launch into false accusations (I witnessed it). The accusations serve no purpose other than to injure one's reputation. They're not only false, they don't solve any problem, they're evil for its own sake. They spring from a malicious core, a mind so steeped in misrepresentation, that deceit and slander are its coins. The character that permanently intrigues against others is inhuman.
