He exiled and murdered members of his family
Caligula had a number of health issues that rendered him very unwell when he briefly became emperor. People thought he had been secretly poisoned or that someone had put something poisonous in his food. Caligula appears to have lost his mind in his own palace at this point despite being recovered. He started murdering those who were blood relatives to him and even exiled them to the border. Caligula personally killed his cousin Tiberius Gemellus and his adoptive son, which had an impact on Caligula's grandmother, who passed away soon after. Her death is the subject of rumors. Some claim that she committed suicide, while others suggest that Caligula most likely poisoned her. Both theories have different meanings and persuasiveness, especially when you read that Caligula wants to remind people of his power by repeating the phrase, “Remember that I have the right to do things anything to anyone".
The fact that he rose up and declared himself to be a god at that time was concerning. He began to build a bridge between the temple of Jupiter and the palace in order to meet the deity. Additionally, he started making public appearances while dressed as various gods and demigods, including Hercules, Mercury, Venus, and Apollo. When he first met politicians, it is known that he started to think of himself as a god; in fact, he is occasionally referred to as God Jupiter in official documents. To fulfill his quest to become a god, Caligula grafted his head onto various body statues.
