To ask why the Zetas are violent is to miss the point of the Zetas.
The main mission of the Zetas is not "supplying medicines". The main mission of the Zetas is to monetize violence. Drug regulations as currently structured accounts for about half their revenue; if they were legalized, that percentage would go down, as likely would their overall revenue, but they'd still be running protection rackets, human trafficking rings, and any other scheme they can devise to reliably earn a return on their investment in a gigantic paramiltary pyramid scheme.
The Zetas are not an overly-zealous pro-drug advocacy/action group. In fact, that's a deeply weird thing to think about them.
Also, I don't know who you hang around with, but I don't know a lot of people who idolize the Chicago Outfit.
Well that makes sense then, I suppose. Do you have any citations for only half their money being drugs?
As far as idolization, HBO runs a series called Boardwalk Empire where the Chicago Outfit and others are portrayed as heroes. Plus tons of Italian mob movies have very positive portrayals. Maybe I'm wrong here, but it seems a lot harder to do a positive portrayal of Mexicans that like cutting civilians' heads off.
