Excellent posts. It may be further demonstrated that reason does not lead to morality, but rather to a state rather more like the organism in the remake of "The Thing". Utterly superior, utterly immoral and wantonly, indiscriminately destructive.
Without God, there is no morality because God is a symbol for Objective Morality aka, an absolute Right and Wrong which does not change according to context.
That is why philosophies such as Marxism and Satanism (aka Thelema in the Aleistair Crowely system) rapidly and inevitably lead to violence, needless suffering, licentiousness and self-annihilation, regardless of the overtly held/expressed motives at the root of the movement.*
*Though he professed that his brand of Satanism was "benign and centered on love and freedom" Crowley is widely thought to have engaged in pederasty human sacrifice, specifically child murder in several of the poorer, less-civilized nations in which he travelled ( such as Arab and sub-Saharan African nations).
