Religious indoctrination in the scheme of evil
A popular song from the 1960s still resonates, What the World Needs Now Is Love Sweet Love.
How true, of course, given the history of human obsession with war and brutality. But also urgently needed is critical thinking. That is, there is so much ongoing damaged caused by belief in ancient superstitions—Christianity being the champion superstition, i.e., it has survived for two millennia. It created a perfect blend of superstitions, gleaned from the cults of the ancient world: (1) the idea that a god was going to send a savior/rescuer/messiah to save its chosen people; (2) after the Romans destroyed the Jerusalem Temple, animal sacrifice to appease god for sins came to an end—and so Christianity resorted to the grim belief that a single human sacrifice would do the trick; (3) when this human sacrifice resurrected, this had major magical impact for those who believed in it, i.e., eternal life. What a formula—and people still believe it!
