>I deserve an explanation how the fuck there are monsters amongst us
What if (You) are an incarnated extraterrestrial spirit?
What if that into which you incarnate is an exquisitely engineered Simulation designed to reify the innermost thoughts of the Children of Men?
In this case, asking why monsters exist is like asking why our image in a mirror exists.
Perhaps that for which you seek an explanation could be rephrased as I deserve an explanation how the f–k there are monstrous thoughts in our heads.
