True, even if we feel like doing ad things in a revenge we need to consider that forgiveness is way better than harming someone, lets start our life and get peace than planning and destroying our life to revenge others.@Kirubel and @Shafaq Iqbal , you are all right, hate is not good and love is the only good, and God will be happy for us if do good, and since we are humans, weak and vulnerable we can not avoid hating someone who may do wrong to us but we can give the person our forgiveness and love prevails.
