"But... he was your child. I mean he.." Anna still wasn't able to comprehend what she should say at this point. It Was very difficult for her not because she felt that conversing with Klara was difficult but because she felt that Chris was still the person, the first child she loved.
"I don't hate Chris. That wasn't his issue and in his hands from where he was born but I was the one who brought him up. It was my mistake that I Wasn't able to take care of my child but he went into really wrongdoings. Killing innocent people, doing rapes, and exchanging slaves... disgusts me truly. I never wished to raise an animal instead of a human."
From her tone, she already guessed that Klara doesn't hate him at all. She just have done it and accepted everything so that it would be easy to live with this guilt in her mind.
