Medusa should always be a monster
It's more interesting if Medusa, when portrayed as a victim, is also monstrous instead of beautiful.
The Greeks used Medusa in shields and other objects as a form of apotropaic magic, a way to ward evil and the evil eye. And she wasn't a pretty lady with snakes, she was a monster; she needed to be to offer any protection.
A few modern works look back at how Ovid tells the story Medusa as a victim, because of how she was victimised by the gods and then by Perseus. But she's usually depicted as a beautiful, demure woman whom no one can really see because they're turned into stones, and I think that robs her story of poignancy.
Medusa was turned into a monster by the gods. She wasn't just punished, she became a thing to be reviled and to provoke disgust.
It's much more interesting to challenge the audience to sympathise with this winged, ugly, demon-looking creature with the hug teeth and the crazy eyes - to dare the watcher to recognise the humanity in this creature damaged beyond any repair - than it is to ask them to sympathise with a sad snake woman with her tits out.
A lot of art, both modern and otherwise but especially recent ones, can only perceive "good" as a part of the beautiful or the nice; a condition to deserve love and empathy, when things just aren't that cut and dry. Many victims become abusers themselves, many people who get these patterns installed on them as children go on to become "monsters" in other people's stories, and that creates very complex feelings on a lot of their own victims who find it hard to square the sympathy they feel with the damage they caused.
To me, that's the crux of Medusa. She's ugly, she's a monstrous killer, she might even be evil, and she's deserving of sympathy and undeserving of being reduced to this.
I think it'd be way more interesting and challenging for a work to provoke you to feel bad for this creature, and to show how even creatures that are not beautiful and are not nice still are not deserving of being treated as she was.
In a way, that's what The Lord of the Rings did with Gollum. His end isn't triumphant and happy for the heroes. It's terribly sad that this pathetic creature succumbed to the power of the Ring, but it was Bilbo's pity for Gollum that saved them all in the end. Had Bilbo killed Gollum outright, Frodo would have succumbed to the power of the Ring and Middle-Earth would have been under the thumb of Sauron, but his compassion - even for something as ugly, deformed, twisted, and evil as Gollum - prevented that. To me that's beautiful.
