When you think about it, what Zaheer does is giving people a chance, even tough his methods are radical. If killing leaders brings chaos, then it is more the people's fault than the red lotus. But, what they have is the chance to choose how they live their life. It could very well bring chaos, new tyrants, or even, if we're optimistic, a state of PEACEFUL anarchy. (for those who may not know, anarchy isn't chaos, but simply the absence of leaders) This would be an intersting subversion, but I doubt a mainstream show would have the courage to show a working society without hierarchy, it would be too dangerous an idea.
By the way, feel the softness of my velvety first post!
