Caligula Malayalam Short Film: Why did they choose 'caligula' as the title?

Caligula is Malayalam satire experiment movie based on caste separations in society. Caligula was a Roman emperor. He attempted to instate his favorite horse, Incitatus (“Galloper”), as a priest and consul, and ordered a beautiful marble stable built for him, complete with chairs and couches on which Incitatus never sat. Once, at the Circus Maximus, the games ran out of criminals, and the next event was the lions, his favorite. He ordered his Guards to drag the first five rows of spectators into the arena, which they did. These hundreds of people were all devoured for his amusement. We can find many examples to prove that he was not a worthy leader. So we decided Caligula is the apt name for the leaders who are not worthy to rule.
