Exactly he knows that her knowing would hurt her and he loved her he didn't want her to suffer but at the same time he loves her he wanted her to know and be there for him and the absence of any interest from her part made him resentful he isn't a good person yes but that takes nothing of the traumatisme that was his whole life

I think it's also because he himself was disgusted by what happened to him, if he couldn't accepted it then how could she, and the truth is that Annette before meeting Katy wouldn't have been able to neither understand that what he and the others kids went through nor sympathise with them, this actions would need her to understand that her father wasn't a good person and all the wealth she was enjoying was built on the suffering of others, it demands a lot of self deconstruction to not only understand and come to peace with it

Yes she canonically could not. I remember the scene which they introduced him to her as “he survived months of torture and all his comrades died in the process” and she was like “good job ヾ(❀╹◡╹)ノ~”. Yes it was wrong of him to idolise her without knowing her but it was also obvious that she had no regards to their lives at all. She lacked basic human decency then and her character development is very fulfilling
“ I WANTED ANNETTE TO UNDERSTAND, BUT I NEVER WANTED HER TO KNOW.”
BTCHHH PLS?! How is she gonna UNDERSTAND if she doesn’t know ughhh
