Why did religious Christians execute accused witches despite ‘thou shalt not kill’?

I have learn that church religous humans are the biggest hyprocrites and biggots only because someone had a diffrence in beliefs. I have been getting info in my towns local library about Mary Eastey. It was cruel and horrible how Mery Easty was treated it was so unfair what was done to her. Why in the past centuries chruch religous people did this horrible things to woman only because they were accused of church members without having the proper evidance?
