do u think that LOVE could change this world?????

I believe that love could change the world. If everyboby on earth loved everybody else the world would be a better place. The crime level would drop to zero because you cared about your fellow man and would never hurt/abuse/murder them. People with a lot of love inside of them would greet everybody they meet with the same love and comfort, from their parents to the homeless person in the alley to the richest person in the world... So much could change, but would it be possible with all of the hatred and war in this world... ?
