1) sometimes not killing is immoral,
like when a Dr does nothing to stop the spread of cancer that kills the whole body.
You mean Morality is not Murdering.
2) religion is the act of expressing and discovering what is our purpose and being, thus what is right or wrong, good or bad without being subjective. Just because some religions fail at this doesnct mean you broadstroke them all. Without the ones who are right then the ethical questions become gray areas blinding proper decisions and conclusions, making them subjective to both polarity sides.
Morning Star(messenger of kingdom in death)
Evening Star (messenger kingdom of life) is the perfect example of that subjective tug of war, and to throw both out because one is wrong, is to ignore the voice of reason showing everyone that mistake of the other.
=post fails, because it throws the Liberator out with the bathwater. ;-)
