The book was great but it kind of bugged me how Harry and several other characters were bad mouthing all of Harry's decisions from Changes. He was in a horrible situation with no perfect outcome but I don't see how it could have gone down any better than it did.

If he hadn't gone after Maggie than Macoy and Harry would have died and the Red Court would have crushed the White Counsel easily considering the shape they were in at the time. No White Council and a victorious Red Court would have made a the problems they are having right know look like a joke.

If he hadn't killed Susan than his entire group including himself, Maggie, and Susan would have been killed. After than the Red Court would have eventually overwhelmed the Gray Counsel and probably killed most of them before they managed to escape.

And finally you can't really say that having Molly help Harry kill himself is entirely Dresden's fault. There was the small matter of the fallen angel pushing him over the edge at the crustal moment, not to mention the fact that to actually pull of the suicide there really wasn't much choice other than to involve Molly. She was the only one who could actually pull off the magic required.
