Why was Nero evil

Nero was called evil because during his reign of Ancient Rome, he set fire to the entire city of Rome and watched it burn, as some said he played his fiddle. He blamed the fire on Christians. Nero wanted to be a musician rather than a emperor and he felt that Rome didn’t appreciate that so he often visited to other regions to play for them. He also watched too many area competitions when he had to focus on Rome. When his mother pointed that out to him, he had her murdered.
