Human nature. And that’s precisely the problem with religion. Most influential religious dogma are simply sugar coated human nature. The fact that it needs to be coated shows that it’s actually something we would normally be repulsive.
I don’t know if God is behind any religion. Maybe God is indeed behind the original religion. A BIG IF, whatever that mean. However it means practically nothing because we’re not following the original religion. We are following modern interpretation of ancient religion.
While I don’t know if God is behind any religion, I know for sure that corrupt officials and tyrants are behind most religious doctrines.
There are sick and cruel people everywhere. What you do not know is that sick and cruel people are indeed everywhere and most people.
It just that we bullshit even our selves that we aren’t.
Humans mainly care about themselves and their family. They also want to max out control of other humans in their greed for power. Also what makes humans happy is relative success rather than absolute success. Hence, humans instinctively want to fuck over any happiness if those happiness belong to others. That’s our true nature.
