Evil is itself a subjective term. It is not possible for anything to be objectively evil, even if every person who has ever lived agrees - which they definitely don’t. To be “objective” it must be measurable, supported by facts; “good” and “evil” are not.

Prove it.

What? RTFA. 2 boys were charged by the Sheriff’s department. They didn’t face any punishment from the school, but law enforcement definitely investigated.
