The meaning of SORRY for him

Say sorry for what? If we do wrong thing, 1 sorry 4 all the false? I kill u i say sorry to ur parent? I rape u i say sorry? USELESS 4 SORRY! We must face b the false that we ever done, all the false will keep going even u give 1 simple word sorry, the person is hurt by u say sorry is nothing. maybe he looks ok, and he accept ur apologize, but inside his heart, the scar still there...
