I understand your point of view. Of course I simplifed his reasons too much. But still, I have strong impression that he was too 'romantic' and passionate to be a winner who would remain in the history of mankind as one of the greatests rulers. His war in Russia was unbelievably daring plan, for example. Did he just want to be equal to Batu khan and others who had taken Moscow too? I would not be surprized at all. Again, it is just my personal impression, it can be far from reality of course.
