Do you know any history of his rule? He was the bloodiest most expansionist and slave oriented emperor of otherwise the most oppressive empires in all of history.
I read his "Meditations", and what I found there was mostly related to better ways of dealing with everyday hardships, and not a "justification of mass death and conquering of an empire". As to your claim about him being the "bloodiest most expansionist and slave oriented emperor", I think this is simply factually incorrect. Seems like you have a gripe with the Roman Empire in general, and you are missing the point of this thread.
