Well, I didn't say this one was wrong, did I? But it's not going to to work with just about everybody.
There's some of those "bad guys" you can reason with, strike truce and deals. Take advantage on that, too. Besides of shoving the dim-witted ones against each others and fighting the ones who are too clever to fall for that. There's not one single method to employ, use everything we got. Assign manipulators, warriors and negotiators. There's plenty of those here, right?
