Why did Medusa hate people?

Medusa didn't actually hate people, she hated men. She was raped by Poseidon, god of sea, that was seen by Athena. Athena hated Medusa for it even though it was not her fault, but she still got cursed by Athena. That's why Medusa hates men, because she got turned ugly, turns people to stone with her eyes and got raped by a man. If I was Medusa, I would also hate men.
