How “Evil” was Commodus

i have also viewed the movie “Gladiator” and i believe that the portrayal of him in that movie was a somewhat true account on who he really was as a person. According to Historia Augusta, Commodus killed many people, had sacrifices performed and other various methods of death by his hand/association. This seems as if he was just a ruler gone mad with power or he really had a thirst for human suffering. Even in his childhood he was “gluttonous and lewd” and a trickster. Maybe he did not mean intentional harm during his jokes. However it looks like he honed into a violent nature based on the outcomes of his humorous times. These unintentional moments started a thirst for his violence side and he grew a custom to this nature of himself.
