I'll read the full article after I'm done eating and will edit this post, just wanted to post my thoughts on the second passage you quoted.
I never really liked Paolini, because to me, he always was just a worthless copy of Tolkien with some elements of Star Wars and Dune thrown in as well, with no real originality whatsoever. He joins the ranks of many such authors who publish books on elves, trolls and orcs here in Germany.
The only thing that was remarkable was his age, I mean at 16, I can well understand why he wrote the way he wrote. But now with 25... I am really shocked and would have expected more from him. I have not read the book - nor do I plan to - but if indeed what is described there does happen in the book... very poor performance, Mr. Paolini.
OK, now I'm actually quite disturbed by this. The passage summing it up sounded bad but some parts, especially the treatment of Sloan and of the child are really... evil.
To conclude, I dare say that Túrin has nothing on Eragon when it comes to evil deeds.
