Are crime statistics biblical? 
All crime statistics tell you is how the current population of people are handling society. Since the society in general does not believe in God, then people will act out there predominant faults, which may be aggression for some races, but it is a Godless society that leads to this. Aren't are physical bodies less than our souls?
Is every county in Africa extremely unsafe? 
Isn't the world in general unsafe? I would say yes, because people do not believe in God like they should. If we all followed God like we are supposed to, then everyone will get in line where they should be. This ranking is determined by God, not by man. If I am wrong, then please use the new testament to show where Jesus spoke to this.
I think this is the same as what Everlast22 is saying when mentioning the word enslavement. In other words, we all have a natural hierarchy determined by God, some are called to rule and some are called to serve.
You're only taught how to recognize and
conquer your vices if you are properly catechized..the Church used to do that in Africa
Yes, and shouldn't we still try to do that. Do you think that we can't catechize people anymore? Are we so afraid of dying for God, that we can't try this anymore?
Just giving food for thought. I do not have the answers.
