Why the girls at salem accused other people of witchcraft

They accused other girls of being witches so they wouldn't be punished after being found in the forest alone.

Explanation:

Back in those days and signs of "rebellion" is punished very harshly so instead they blamed some women from their town and another girl that came with them. To prove that they were witches they would fake seizures and sickness and do the witch trials, some of which included drowning the accused witches, and if they die they were normal, and if not they were a witch so it was really not fair.
