Oh hell, Chad is neither innocent nor victim (IMO) and I hope my novel doesn't come across as such. I'm just sayin, when it comes to the kids, someone had to pull that initial (metaphorical) trigger, or swing that (metaphorical) bat, or drug that ... drink, and I believe it was Lori. Killing adults is one thing, but killing a 7 year old, and your own freakin daughter? That's an entirely different species of monster. I M O. Chad probably suggested it, he could have insisted on it, he could have invented a whole set of rules and regualtions around it, but Lori did it (IMO). Once Lori stepped over that line, I think she took the reigns and she probably suggested, nay insisted that Chad kill his wife (IMO), and I don't believe it took much cajoling on her part. He did it willingly, whole-heartedly, and came out of it a little too enthusiastically. Still, those short clips of the two of them in Hawaii - looks like she's in control. Just my O, ya know?
