Why did Perseus cut off Medusas head?
After King Acrisius sent Danae and Perseus away from Argos, they came to a land where the king collected wives and he wanted Danae as a wife, but she refused, so he sent soilders out after her(After what must seem like the millionth time of asking her to Danae) And Perseus beat them up and sent them back and told them to tell the King she would marry who she wanted, so the King, (Obviously being really mad At Perseus) Wanted Perseus killed so he told him to go and kill Medusa thinking he would be killed, But he got the head as asked and brought it to Athena (And Yes King Acrisius was killed by Perseus like in the prophecy) THAT is why he cut Medusa’s head off.
