Plutarch

I want to know what people think of Plutarch. Is he good? Evil? Self serving? A real ally? What do you think of him based on what we have gotten about him? I was discussing him with a friend earlier and they are dead set on thinking he is solely evil and self serving, but i dont think so. So, let's discuss Plutarch. Would you want to see a book on his backstory that delves further into his childhood up to when we meet him in SOTR? I think he is teetering on the line of good versus bad. He has more empathy than most capital folk, but he is also very self serving.
