It justifies force, conflict, struggle as proper ways for man to ensure his survival, rather than negotiation and rational compromise. Man is never let free of his supposed status as a wild beast, who must "kill or be killed." In fact, neither "Darwinian" materialism or socialism has any room or rationale for human freedom at all.
We recall that this earth became a domain of the one referred to by means of the King of Tyre in Ezekiel 28, . Some tend to think that with a close observer's mastery of the systems and substances of creation, as the one intended to be the living signature and gaurdian of it, he was able to pervert it. Then, God created a guarded enviornment as a new world* in its formative stages, for His planned new Lords of Earth (apparently amidst such perversities as animals that had developed their livelihoods by eating other animals). Some opine that the mandate to be a servant to God's Intended, His appointed Lords of Earth (mankind, "the sons of God") may have been the last straw with Lucifer in his regards of God.
Interesting conjecturings. I'd be interested in your reflections about such matters, as the Lord and you may allow.
