Even if this is true, I'm not sure this is a torture worthy offense? Like bold and controversial opinion here, but torture bad.
I absolutely can blame you for wanting to torture an innocent person. Its like you don't see merlin's daughter as her own person, and only see her in the context of her relationship with merlin. Like she's just a tool you can use to hurt merlin. Kinda gross in my opinion.
People aren't tools, merlins daughter is not complicit in merlins crimes. We dont even know her opinions of mordred or what merlin did, she acted at least kindly towards mordred as a kid.
