I thought both of those women - Monika and Helena - were amazingly strong. Imagine having to face a woman who's life your father had completely ruined and imagine meeting up with your tormentor's daughter. Really incredible, but hopefully healing for them both.
I think you are right, Paws. I think Monika had distanced herself from her father (she refused to call him father for a start), but hadn't yet come to terms with the fact that her mother was complicit in what he did (whether that be through fear, loyalty or whatever). I've no doubt it was hard for her to imagine her mother being fully aware of what was going on and doing nothing to stop it - and then, seemingly, lying to Monika about how aware she had been. That must have been an impossible thing to live with for her too.
I do wonder, however, whether if there had been no war, Amon Goeth would have ended up imprisoned for murder anyway. He just seemed to be so fundamentally sadistic. It seemed that Naziism just gave him the excuse to do these things with impunity.
Chilling stuff, but great to see these strong, warm women battling through it all to make better lives for their children. Funny how it always seems to be women picking up the pieces after these horrors...
