He went off the rails after his mother’s death

The majority of historians concur that after his mother passed away, Nero's leadership entirely transformed, possibly on his own initiative. His mother was Julia Agrippina (The Younger) who bore him in her first marriage with Gnaeus Domitius Ahenobarbus. Julia Agrippina was the daughter of Germanicus and Agrippina the Elder.When Claudius became emperor in 41 A.D. Agrippina (his niece) was recalled from exile and allowed to return to Rome, and her estate was returned to her. In 49 A.D. following the fall and execution of Empress Messallina, Claudius married Agrippina, and many things changed for the young Domitius (Nero).

In addition to losing all sense of reality and attempting to get admiration by performing the most bizarre acts in front of others, he also lost his sense of right and wrong. And because he was the emperor, no one could stop it. This led to odd performances as an actor, singer, and even in sporting events and gladiator contests. Nero was always the victor, and he frequently paraded through Rome's streets holding the prizes from his fictitious competitions.
