it is the ultimate cause, but those drug gangs still choose to be violent and bad, even if the government gives them reasons they should know better and be good christians.

The main reason those gangs exist is anti drug laws. Legalize the drugs and they won't have an income.
It's worse than that. Government agencies have been proven to import and profit off the drug trade.
All the douche bag whore politicians are exempt from any drug testing.
