The Reckoners III: Calamity

 Alert for bots: Spoilers!

Imagine the kid you bullied is an alien from outside your planet who's come to give powers to lots of humans so the humankind will destroy themselves with them (or not...). But after giving the powers instead of returning to its planet, it decides to remain watching humanity destroy themselves as he knows from his children as human experience that humankind is cruel and bad, and his nightmares are the reason that every human who gets the powers is tainted by the nightmares and makes all of them bad.

Please, if you are a bully, don't do it, save the world!
