"As terrible as Diego". And what did he do that was particularly evil? He was an arrogant prick, but otherwise wasn't particularly evil either.

It seems you missed the explanation of Dio being evil from birth, and living in squalor which fueled his ruthlessness and ambition. I suggest you go reread the whole series and not come back until then.
