Personally I'm not in favor of a mercurial personality, I would rather maintain an attitude that is reliable through positive and negative events. Whether that attitude is good or evil is an entirely other discussion. I would, if given the choice, lean towards a more matriarchal tone, where the faithful are praised like obedient children and the dissenters are treated with sorrow and compassion and the hope that they will see the error of their ways. I just see it as a more effective way forwards, better for disarming our foes and adding numbers to those who follow us.
