It depends. I believe that Plague rat has a way to reduce damage, in which case the Demoralize won't do anything, and he'd stick around getting stronger and nastier waiting for Visionary to come out of hiding.If the villain and environment don't have a way to destroy ongoings AND they don't have healing/damage reduction or an alternate win condition, then it could be very useful. But it could also let the villain build up and heal to the point where Visionary would get stomped.
