Iv'e been rereading some of the stuff I read when I was 10-14 (It is hard to match how much fiction you can read that age). Mostly fantasy. What you say is very true. Both that disturbing scenes are more disturbing to me as an adult. Also as a kid you read the story, while the larger themes might escape you.

Otherwise it is fascinating to reread, books you loved as a kid are dross, while others are even better as a grown up. In my case David Eddings and Robin Hobb.
