Please see my new article in The Times of Israel called “Monsters and Humans.”
Ultimately, the litmus test is whether there is a human in that being. If there is that spark of G-d, that soul, that inner conscience weighing right and wrong, that fear and love of G-d and his creations driving decision-making, then there is still hope for that person as well as for mankind.
However, if we are dealing with those who are sadistic animals in human form, then we must be as soldiers of Hashem, taking a firm stand and decisive action, because true evil does not remain dormant for long.
