A lot of how this one will be taken depends on how much you can accept the protagonist's view of things. There are some fine and healthy bits of hypocrisy. Healthy because, to my to my sensibilities, hard cut and unbending stances are unmerciful at best, inhuman at worst.
Anyway *waves away*
I was entertained. I like it when the books focus on the characters friendships, and there was a lot of talk on loyalty. I'm also a bit amused by this trend where the dead body was a poor excuse for a human being. It says quite a bit about a hopeful outlook of humanity, where the ones getting killed are the despicable creatures that push everyones buttons beyond the limit.
Of course, then it goes and balances it with the little crazy shit that actually did it, so a bit of fast-stepping on that one.
Not as great a time killer as the first volumes, but better than the one before.
