Love is that essential ingredient that makes life worth living, it seeps into every corner of our lives and where real love is evil can't be there. Where love has the upper hand devious and cruel existences can't survive, happiness is the only thought that survives.
Evil religions have conditional love hence they are evil. But real religions walk the "love walk". Whether you believe or not you need love to survive and enjoy life the best you can otherwise it will leave that empty feeling in the pit of your stomach.
