People used to marry in their 14-15's all the time back then, even nowadays in Japan the age of consent is 13, in Sailor Moon Usagi dated Mamoru and the age gap was something similar ( She being 14-15 and he being a fresh college student in his 19-20 )
So yea, saying its "creepy" isn't an argument, sorry.
besides, she ends up with a guy like 40 years older than her, which is 10000x more creepy by your own logic.

But fine, I'll give to you that is possible there is a alt DIO that has rape tendencies, but you should also admit that it was Araki forcing Diego to be a villain, just throwing in the trash all development he had going on for him during SBR.
