Certification for being a brutal warlord in the post-apocalypse is super-lax

I feel like Caesar isn’t uninformed or stupid (the opposite actually)… but since he knows he is the only person with any semblance of an education he can just spew the biggest bullshit known to mankind and twist facts and words to convince his people to follow him. Really, who would correct him? Plus his ego is so big that he doesn’t accept criticism anyway, and since his people love him so much they don’t accept criticism of him either. Boom - you’ve got your infallible god-emperor. But wait, Caesar is humble so he isn’t the god Mars himself, only his son. That makes his bullshit story more believable because he is still mortal. He’s very intelligent but also the wasteland’s biggest grifter.
