I remember this one Julii family member in RTW. I forget what his name was, but all his pre-battle speeches involved: "The enemy may have the Moon People on their side. But we have lovely hats, which will protect us from their fearsome gaze." Obviously his traits indicated that he was mad ( he often painted his backside purple and he would drown spiders in vinegar, since he believed they were complicit with his enemies ). But he was a successful general, despite his short-comings mental health-wise.
