In some thought experiments its fully the latter, in some others its a mix, in some its even further beyond.

"If my utopia is to exist, then there must be no way for it to backfire! I'm 'mad' but I'm no idiot. Just like how they called me a 'fool' for wanting to build machines that don't have planned obsolescence designed into 'em. What's the point of something NOT BUILT TO LAST!?"

Imagine a mad scientist has some grand plan for solving all the world's problems with their own special solution.
However, they refuse to enact said plan until every single solitary hitch in the plan is ironed out, and is the only reason the world order hasn't been upturned yet.

Doctor Deetz is a caring, empathetic and responsible scientist.

But she's still a bit of a *mad* scientist.

She'd never act on it, but she still has dle fantasies/thought-experiments of enacting the perfect global bimbo utopia via unleashing an infectious bimbo virus.

She'll spend whole lectures on how Bimbo doesn't need to be a 'degrading' or 'diminishing objective and then toil away in the most secure reaches of her lab on the most absolutely depraved, indulgent, brain-frying and degrading bimbofication vectors you've ever seen.

Sure there's a wide spectrum to what being a bimbo means to others, but she'll never deny the allegations of what she prefers herself. 😏
