Acting or real?

I know this is a drama with a cast acting. But what I meant is if her nephew and daughter were pretending to die to make the Consort confess about her sins in order to destroy the incubus demon.But if they were not, then it is sad that they died because of her insanity.I would never give a second chance to bad demons. If they are bad and commit many sins, they have to live in hell forever.

Oh man how could she do that, I can't…

Oh man how could she do that, I can't even think that. Unreasonable. The protagonist group will do whatever they can to defeat the demon.
