What are some of medusa quirks or flaws?

She is forever gonna be alone. That's her curse for getting raped. Anyone she looks at turns to stone. Imagine how alone she is now and forever because she won't be able to have contact with people without turning them to stone.

cold-hearted monster. She was not always this way. Medusa was one 
of Athena's most important servant. She was also the most beautiful 
person in Greece.
