There are stories I greatly enjoyed as a child that I just can't read anymore with new context.

I remember finding out David and Leigh Eddings abused a child that ended up being removed from their care. I tried rereading their books and only a couple of chapters in there were men discussing the importance of beating a child to enforce discipline. I glossed over this as a child thinking it's just medieval culture, but as an adult knowing that this is evidently something the authors genuinely practiced I couldn't continue.
