Prove it

Apparently I'm trying to have a 'monster-off', where Karen and Jacob keep trying to one-up each other as to who is the worse human being.

Karen expresses happiness at Shawn's death, and then lights his re-animated head on fire (twice) before tossing him in the garbage. That sounds awful, but then you remember that Shawn is a murderer. Jacob, however, is grifting two innocent people and advocating that they not discover the truth about their dead son.
