Slow revolutions are also planned, which means that those in charge have some ideas how to do things better than the last lot. Bloody revolutions generally run along the idea of "We're better than those guys and we deserve to have all the privilege and power they do!"
It's also why one of the guys who started the French Revolution met with Madame Guillotine later on.
