So Paarthunax commits war crimes and gets to live, whereas the Ra'zac, who eat humans, which they have to do to survive, get killed. And a baby Ra'zac gets killed. And I'm not buying Paolini's argument that killing them was self-defense. While the first one was admittedly about to eat Eragon and Arya, the second one was still in its shell. There was no immediate danger. Eragon literally could have put it to sleep. Self-defense my ass. Try getting that to hold up in court.
