Please see my new article in The Times of Israel called “Chutzpah Dating.”It used to be that young men and women went on dates and generally treated each other respectfully and civilly as they explored whether there was a spark between them and potentially a match to be made. But somewhere along the lines, too many Prince Charmings have turned into real ugly toads.
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.
