This is *half* the Minerva I want. She's brilliant, cunning, has this massive over-arching plan, has deftly manipulated an entire cadre of supervillains into something that benefits only her - it's awesome and I love it.
But.
Thus far, all of the maintext and the overriding implication of the subtext is that she's doing this to hurt Diana. She says in this issue that this is all about her playing with her food, that the entirety of her purpose is to demoralize and destroy Diana; Morrow backs that up here when he tells her that the whole thing with Genocide was about isolating and alienating Diana. The Psycho thing, the demolition of the DMA, the targeting of Etta, it all adds up to "I live to destroy you, I take sadistic relish in your pain."
That's the Rucka/Pfeifer Cheetah in action, the one who's actually flat-out cruel and sadistic rather than coldly indifferent, whose relationship with Diana is uncomplicated loathing. It ignores that Diana has been friend, resource and savior to Minerva far more often than she's ever been her enemy, and that Minerva is a greedy, selfish collector of knowledge, not a sociopathic predator. The Cheetah is a sociopathic predator, sure, but the Cheetah doesn't make elaborate plans; that's the Minerva half's job. The Cheetah just bloodlusts, which is a very primal, immediate, physical thing. An elaborate plan to cause Diana maximum pain is a waste of Cheetah and Diana's complicated history and Minerva's complex character; that's the sort of thing we have Circe for, y'know?
There's reason to suspect, though, that Minerva has more going here than we've seen. If nothing else, this is awfully early in the story for the ultimate foiling of the mastermind, which Minerva seems to be. So it's quite possible there's still some actual benefit to here here somewhere beyond mustache-twirling "I will make Wonder Woman suffer!", which would make me, already pleased with her supreme competence, totally ecstatic about her overall portrayal.
