Edward Zero: Secret Agent, Sociopath, Hero?

I posted about Zero before.  At that time I said it was a new comic series by Ales Kot [writer] and Michael Walsh [artist] that looked interesting.  Here’s how the advance solicitation described it…

                         SAVING THE WORLD. ONE MURDER AT A TIME.
Edward Zero is the perfect execution machine – a spy who breaks the rules to get things done. When a stolen device appears in the center of a long-running conflict, Zero comes to retrieve it.  The problem is, the device is inside a living, breathing, bio-modified terrorist and there’s an entire army after it.

 I just learned that although the series will contain a series of rotating artists, each doing one issue.  I also discovered a bit more about Edward Zero…

ZERO is a secret agent. Edward Zero. He’s the perfect execution machine, in a sense — throw him at a problem and he wil solve it. Just remember that the way he reaches the solution may not always be to your liking, because he’s a bit of a sociopath.

But what happens when a sociopath realizes ideas and systems he based his life upon are deeply broken and not at all what they were supposed to be?
