they all had some Dark fates.

For DIO, it wasn't just him being burnt to ashes it was what was left of Jonathan's body

Kars is stuck in space frozen. His immortality is even bad for him.

Diavolo got the worse treatment of being subjected to an infinite death loop. Meaning he's dying every time

Angelo is stuck as a stone

Kira is suffering in Hell.

and Pucci got a pretty bad fate too

Kira is a ghost now

Yo, Anjuro
