Regula, the third emperor in Roman Empire, was rated as a typical insane, confused, exhibitionist and sadistic emperor by historians. He entrusted all political affairs to his cronies and led a shocking dissolute life. He is very extravagant. He used gold to build palaces, warships, even saddles and feed buckets, and wasted all the gold in the national treasury within four years of his reign.

Emperor Regula's metamorphosis seems to have his family roots, and his grandfather Tiberius was also a pervert. He built a small stage in his villa in Capri Island, where some young men and women gathered to perform "ring" games, that is, men and women made obscene behaviors such as wearing rings. He also collected many erotic paintings and asked people to play them for him to enjoy. There are so many ugly deeds that they are gradually exposed and criticized. In 36 AD, Regula thought that his grandfather Tiberius's behavior endangered the existence of the family, so he sent someone to suffocate him alive with a quilt. Of course, Regula is no better than his grandfather on this issue.
