"Using any opportunity, he is said to have married an old woman for her wealth, and in the same vein, participated in the Steel Ball Run for prestige."

Taken straight from Diego's personality section, it details that he will do anything for prestige. The older woman mentioned happened to die six months after she married Diego, which we can presume as Diego poisoning her because she was not only rich, but it mimicks Dio poisoning Jonathan's father in Phantom Blood. Diego will sacrifice anyone to climb the ladder, mainly because he feels the world has wronged him, which started from an early age. The whole idea that you are "born evil", is a weak way to show a villain's level of villainy from a critical perspective. Diego was an attempt to take Dio's flawed aspects and correct them, all while keeping himself comparable to Dio. Scary Monsters is kind of like a Stone Mask in a way, which is why I don't see a problem that Diego somewhat stole the stand. Dio is just an evil guy that was born evil and was poorly treated, but no explanation further. Diego is an evil guy that mimicks Dio, but improves by actually having a detailed backstory that will actually give Diego some sympathy despite how generally terrible he is. Might not be the most amazing backstory, but at least he has one unlike other Dio's.
