Well, that bit with Beast is only assuming that Medusa didn't have a totally baseless heel turn and change character for the sake of plot convenience to become the benevolent Inhuman Queen that everyone's meant to love. Medusa went from someone who was cool with murdering Cyclops for destroying one Terrigen cloud and in theisissue when Havok confronts her says,
"I gave the order -- but your brother left me no choice." which is in and of itself pretty bullshit.
HOWEVER, when you look that in addition to that, she's been letting mutants suffer and die for EIGHT MONTHS, and had prepared explicitly for waging war against the Mutants if they retaliated (which Beast overheard which is why he went to the X-Men in the first place rather than tell her) she went from this—
…to this
Who says in the afterwards,
"There's no question in my kind that I did the right thing. Our species ability to transform through Terrigenesis does not outweigh the lives of even a single Mutant, much less ALL of them."
One Mutant?
Jamie Maddox? Cyclops? Alchemy?
Because when three Mutants died and tried to do the exact same thing as pushing that fucking button, she was a completely different person.
