Every time I see one of these stories, it amazes me that we're in the 21st century and we still have exorcisms taking place that kill people.
In this instance, a husband and wife were beaten to death by their son and nephew.
According to the son, he had, "had no control over [himself] and it was as though [he] was under a spell."
Indeed he was. It's called religion. And it's a spell that needs to be broken so these things don't happen for such worthless reasons.
