I don't actually have a strong opinion on the matter, but keep in mind the OP is advocating killing people to improve the state of the country. In the abstract. It's "kill the narcos", not "if a narco rackets or threaten me", then I'd be justified in taking him out".

For me that's quite a line to cross.

Start fighting using non-violent means and maybe only resort to violence when confronted with violence from the other party.
