Do not repay evil with evil

My sister posted this quote on Facebook today,


 "I mourn the loss of thousands of precious lives, but I will not rejoice in the death of one, not even an enemy. Returning hate for hate multiplies hate, adding deeper darkness to a night already devoid of stars. Darkness cannot drive out darkness: only light can do that. Hate cannot drive out hate: only love can do that" -- Martin Luther King Jr




It strikes me that as awful as Osama bin Laden was this should be our attitude, because we should never hate someone, or rejoice in their demise, simply because they are evil or did evil things.  Ultimately it is God's responsibility to punish those who do evil (although He has provided us with a judicial system that helps in some punishment on earth).  


In Romans 12, Paul says
 "¹⁸If possible, so far as it depends on you, be at peace with all men.
 ¹⁹Never take your own revenge, beloved, but leave room for the wrath of God, for it is written, "VENGEANCE IS MINE, I WILL REPAY," says the Lord.
 ²⁰"BUT IF YOUR ENEMY IS HUNGRY, FEED HIM, AND IF HE IS THIRSTY, GIVE HIM A DRINK; FOR IN SO DOING YOU WILL HEAP BURNING COALS ON HIS HEAD."
 ²¹Do not be overcome by evil, but overcome evil with good."


Wouldn't it be a wonderful world to live in if this was the attitude of all people?
