According to the Bible's creation story, Adam and Eve were the first to commit sin. However, I disagree with this narrative, and I'll explain why.
Let me begin by stating that according to the Bible, God has infinite power (
Psalm 147:5;
Job 42:2;
Daniel 2:21), infinite knowledge (
Psalm 139:1–6;
Isaiah 46:9–10;
1 John 3:20), and is present everywhere simultaneously (
Psalm 139:7–10;
Isaiah 40:12;
Colossians 1:17). Having established what the Bible claims about God's omni-attributes, I will continue with my viewpoint. In my opinion, God committed the first sin because he created Adam and Eve with the foreknowledge that they would disobey him after he used the serpent to deliberately tempt them with a forbidden fruit. According to the creation story, God not only punished Adam and Eve for their disobedience (which he knew would happen), but he also punished the serpent for doing what he knew it would do. He also unjustly cursed the rest of humanity with a sinful nature for Adam and Eve's sin. Finally, he devised a sinister plan to brutally kill his own son by torturing and crucifying him in order to atone for his original sin of creating humanity with the foreknowledge that they would become corrupt.
If God is all-knowing, all-powerful, and ever-present, as the Bible claims, then surely he would know better than to create Adam and Eve (and the rest of humanity), knowing that he would later regret creating humanity and repopulate the planet with the same morally flawed humans that he just annihilated in a global flood. According to
Genesis 6:6, he regretted creating human beings as well as every animal, every creature that creeps on the ground, and the birds of the air. Thus, he carried out his devious plan to annihilate humanity in a global flood, except for the devout Noah and his family (
Genesis 6:7-8).
In accordance with what the Bible states, it is my opinion that God was morally depraved (sinful, evil, sadistic) to first create Adam and Eve knowing that they would disobey him and that he would punish them for their disobedience; second, he punished and cursed Satan (the serpent), despite using Satan to carry out his nefarious plan to tempt Adam and Eve into disobeying him; third, punish and curse the rest of humanity with a sinful nature because of Adam and Eve's disobedience against him, despite the fact that the rest of humanity had nothing to do with it; and finally, he brutally tortured and killed his own son to "redeem" humanity for behaving exactly the way he knew they would behave before he created Adam and Eve. I think that is truly evil (
Isaiah 45:7).
