Here's an advise for people who hate someone: If you hate someone, just think about suddenly being notified that the person you hate is dead. Do you feel ANYTHING? If you don't feel the satisfaction of them being dead, the you don't hate THEM, but just the thought of them.
Hatred, or any other negative emotions held for too long can be as bad as smoking cigs every breathing moment. Come to terms with them, by holding on to them you're not doing yourself a favor, rather destroying yourself. Don't do that if you REALLY want happiness.
