Why did the Romans engage in so much debauchery?

eating until they were sick is probably an urban myth. No more than people do that today. There was a story about Caesar talking of him retiring to his quarters to vomit, and they had a thing called a vomitorium, which was not for vomiting in, it was a type of stadium where visitors could 'spew' out of one open end of it when finished. From these things there was an invention of Romans going to a special room to vomit.

Caesar probably had a neurological disorder or vertigo.

they didnt

only 2 emperors encouraged debauchery -= Tiberius and caligula (actually this was his nickname - little boots - hie real name was Gaius Julius Caeser) - Tiberius being a lot worse than caligula

Certain of those 'debaucheries' were essential God-calming-acts.

Hail the New Puritan!

Learn some fvcking history instead of myths. They didn’t to the first, and not that often to the second. Myths made up by Christians to make them look bad in their up yourself world.

No wonder their civilisation collapsed.

Cultural degeneracy is almost always part of the prologue of civilisational downfall.

Orgy does not mean what you think it means.

Go big or go home?
