How morally corrupt was the Roman empire according to this teaching?
The Roman empire was grossly immoral and bestial in many aspects. It showed no concern for lower classes or conquered peoples, threw people to lions, and became wicked and evil, with absolutely no moral compunctions left, as history confirms its moral deterioration.
Les teaches that in Daniel 7 the fourth beast, described as dreadful and terrible, represents the Roman empire. He notes it was noble in some aspects but bestial in many others. It had no concern for the lower classes or for peoples it overran militarily, throwing them to the lions without thought. With its pomp, success, and circumstance, it became grossly immoral. Les points to The Rise and Fall of the Roman Empire as history authenticating that the Romans deteriorated morally, having absolutely no moral compunctions left—they were wicked and evil.
