Even if he does, it doesn’t really matter. He already caused immeasurable damage to the world, destroyed who-knows-how-many lives and got to live well into his 90s in unimaginable opulence.

Plus he’s stepping down on his own terms, nobody ousted him. None of his enemies ever managed to take him down, and he’s got his legacy all set up. When he does eventually die, it’ll most likely be in a comfortable hospital bed surrounded by some the best doctors in the world making sure it goes as well as it possibly can.

He dedicated his entire life to being an evil bastard and he completely, utterly won. I don’t think there’s anything much that could even hurt him at this point.
