It may be that there are good as well as in every walk of life be it human and alien? Old Indian wise man was asked by his grandson: "Grandfather why do I have both good and bad feelings, and How may I control the bad ones"? His wiser and old grandfather told him: "We all have both a good and a bad wolf within us and all you need do is not feed the bad wolf". That is why God gave us grandparents? Mothers and fathers as well as grandparents all have a vested interest in our well being! If your heart is full of love there would be no empty space for anything else?
