It's not something Rucka invented.
The main difference between Medusa and Cheetah is of course that the latter is way more important as a recurring figure to the WW franchise than the former, so they need to keep it around. But even then, Cheetah can't kill mass quantities of people with just a gaze, and is here actually expressing a desire to be freed from her curse. Medusa didn't want to reform, she just wanted to kill everybody, and there was no time to convince her otherwise without MASSIVE amounts of collateral damage.
That was Euryale, and it's time for a bit of fanwank. Maybe she and Stheno aren't as powerful as their sister? Medusa may be the only mortal one, but her gaze is stronger. Meanwhile, Euryale and Stheno are immortal and can regenerate non-snake heads after they are decapitated.
But he contradicts that text when Medusa turns one of Cale's security guards to stone when he sees her from a security camera. Ditto a handful of guards in the White House.
