POWER by George Orwell, 1984

"We know that no one ever seizes power with the intention of relinquishing it.  Power is not a means; it is an end. One does not establish a dictatorship in order to safeguard a revolution; one makes the revolution in order to establish the dictatorship.  The object of persecution is persecution.  The object of torture is torture.  The object of power is power." – George Orwell, 1984
