Most mexicans the good ones are very catholic and family oriented people.

So it makes me believe that the criminals that are in drug cartels are not religious people at all and worship an evil spirit, such as the devil or a demon. I believe I read something a while back that talks about this and how they have some God of darkness that they worship or something if they belong to the cartel. This would explain why they can kill babies and children with no remorse or second thoughts.

Is this true?

There was a cartel named Knight Templars where the founder Moreno Gonzales was adorated like a god and there was pseudo religious initiation rites.
The situation is the same of all crime gruops they believe in the money not in the God.

Worshipping the devil happened in American gangs:

I think they worship money.

Explain how they accept microwaving babies and killing young children then?

Tons of guys who worship money in organized crime that would never do that shit. It’s something way more evil and sinister behind it.

The killing kids and babies is a disgusting intimidation tactic. Are you going to try to rob them or inform on them knowing what they are capable of?

I think Fleming Avenue has it right, they want to scare everyone. They will also kill anyone who informs, rats or civilians who witness things and tell the police. Killing baby's by microwave is disgusting, but has no ties to Devil worship.

There is Santeria worshiping in Mexico and nations close to them, maybe that is what RushStreeet means.
There is an old movie with Javier Barden about that subject. Here is a wikipedia breakdown of the film. I just read it, and can see where Rush gets the idea. It's sounds very sickening. Rosie Perez was also in the film.

The cartels are paramilitaries, it's a war and in wars terrible things happen.
