For example, he set himself up on the Isle of Capri, where for fun he molested children and afterwards threw them off the cliffs into the sea. Men in row boats were stationed down there to club to death any survivors.
He also raised Caligula there, fostering in him the depravity that "Little Bootsie" (Caligula) would release on the people of Rome. Of Caligula, Tiberius said, "I am raising a viper for the Roman People."
Some people have suggested that Tiberius knew he was depraved and a failure and wanted his successor, Caligula, to be worse, so that Tiberius would not be remembered as the worst Roman Emperor.
I doubt that. I think Tiberius were merely a sadistic monster who wanted to wreak depravity, evil, and misery; he probably got a kick out of it.
Good correction. No Roman Emperor was good, but maybe Constatine is an exception because he mainstreamed Christianity, he was Gods vessel in that way.
