The true origin of hatred is from satan, the enemy. Those who do not love, do not know God, as that is what He tells us in His Word. All men have evil in their hearts until Christ enters in, and that is why we all need a Savior. Satan is pure evil. He whispers false imaginations into our minds and he is a deceiver, a liar, as he is the author of lies, and he has had thousands of years to practice his craft. He will dangle seemingly beautiful things in front of one's eyes to tempt you into something that is not of God. It may look good at the time, but then destruction comes, as he comes to steal, kill and destroy.
