This is the way Christianity was introduced to most of the world not just the new one.

Spreading the gospel in their own quaint way. Showing these heathens how civilized folks behave.

There is truth in this cartoon, but I will not feel much pain. Recently I was reading about Aztec culture. They would hold religious ceremonies where they gave both human and animal sacrifices to appease the gods. Sometimes there would be hundreds of victims. Most were prisoners of war but some were from their own group. They even sacrificed their own children.

Maybe it was a way of keeping the population within bounds.
