The rich did not care who ruled, as long as they were allowed to be rich. The poor could not afford to care and nobody asked their opinion in any case. Only the middle class mattered and any half-witted ruler knows how to pamper them.
Fear is not an emotion, it is a disease. It spreads from the leader to his followers and vice-versa. Nothing has killed more men in war than fear. What should a warrior fear? Death? But death is what everyone achieves ultimately. Is it wounds that you fear? What is more important? A pint of your blood or the nectar of victory? Think. Thinking will clear such doubts.
