christian book touting manly aggression inspires violent fundamentalist meth trafficking cult

To be fair, John Eldredge, the author of the book Wild At Heart: Discovering the Secret of a Man’s Soul is probably not happy that his book has become required reading for a "a ruthless cultic Christian paramilitary fundamentalist crime syndicate that controls most of the Crystal Meth traffic in the US and is fond of tossing severed heads into Mexican discos". Furthermore, it isn't as if the meth gang (La Familia) had been selling Girl Scout cookies before Eldredge's book came out.

On the other hand, the book does say things like:

Aggression is part of the masculine design, we are hardwired for it. If we believe that man is made in the image of God, we would do well to remember that “the LORD is a warrior, the LORD is his name.” (Ex. 15:3)

and

The kingdom of heaven suffers violence,” Jesus said, and violent men take it by force.” (Matt 11:12 NASB) Is that a good thing or a bad thing ? Hopefully by now you see the deep and holy goodness of masculine aggression and that will help you understand what Christ is saying.

and

(quoting Tremper Longman, author of God is a Warrior) Virtually every book of the Bible–Old and New Testament–and almost every page tells us of God’s warring activity… what would Miss Manners have to say about taking the promised land ? Does wholesale slaughter fit under “Calling on Your New Neighbors.”

In a lot of ways Eldredge is a fairly mainstream evangelical who happens to be less apologetic than most about the patriarchal and martial aspects of the Bible. In any case, even apart from Eldredge's influence, the cartel also has ties to a Traditionalist Catholic community called New Jerusalem with its own history of latent sectarian violence which bubbles to the surface from time to time.
