You could be right, then again, I look at him through a different lens,
1. He and JW were probably each other's besties until HMR came along. Then she dumped baby brother, broke his heart, and a new fella was going to be in S's life. How dare she?! Let's get your kid back, and while we're at it, just wipe the whole lot of them out!
2. In my view, he's the most violent, from what's been said at court. He was most vocal about revenge.
3. Very true. He mentioned in a FB post, not long before arrested, that his son was his whole world. (loosely quoted)
4. Look at who we are talking about here. GW4. Are we sure that he hasn't played some dirty pool to get custody of that child after they split? I don't know TB, and her mental fitness, but I do know that G4 is accused of executing eight people, at least in part, to assist his bro in obtaining custody of his child, forge custody papers to get said child, and move both children far away from their maternal families. He's not exactly the picture of mental fitness himself. I've often wondered just how he was awarded custody, and what went on surrounding that.
However, that lens may change as the trials go on. He may be a big wimp when it all shakes out. It's pretty wimpy not to face your enemies, and to shoot mothers as they slept beside their babies.
