Yeah but we can’t forget that she also played a huge role. She also served the spy of that other nation (the queen). And would have continued too if not for the duke. I think it was too harsh to cut him off.
Harsh, sure, but he is too dangerous to keep around.
Okay, first and foremost, the method Franz chose was extremely wrong, however... I can’t say I exactly blame him. He witnessed his mother being poisoned and no one believed him. His sister was also in danger and no one listened to him. He was powerless and desperate for revenge that he was blinded by the enemy's true purpose and was played like a fiddle to do their dirty work while they handled other matters. It was going to end like this either way.
Annette cutting off her brother is also the right decision. He caused problems and now she has to clean it up his mess.
