what did his daughter do, exactly?
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.
