"Dedication" to committing the murders doesn't apply. Being part of the planning, execution, cover up of the murders is relevant. One's mood while voluntarily carrying out the crimes isn't important.
If GW4 didn't want to murder the Rhoden family, he had many months to stop it. I guess he wasn't dedicated to that.
I think maybe GW had the least to gain from the R's deaths... and then I think, what
did he have to gain? Anything? I can't think of one thing as to gain. The inability to say "no" to his mother, father and brother? Probably, imo. AW and JW have obvious motivations and expected gains. I think BW was bound and determined to regain his battered ego by killing CRsr and being top dog again for having done so. I think those 3 had anger and hate fueling them along with their own motivations.
GW is the odd man out, it seems to me.) He already "had possession" of his own child and he may not have felt hate or personal anger against any of the R's. It was said that GW and FR had been good friends at one time. Maybe that friendship got ruined due to GW's family members and their interpersonal problems with the R's and GW had no personal reason of his own to dislike them. It would have been awkward when the rest of the family was having a beef that G's wasn't feeling personally. Maybe GW didn't want to join in on the plan. Why would
he want to? And, maybe he thought the way so many people think when they hear about a plan to kill...
"They won't really do it. This won't happen. I'm not going to take this seriously. Something will happen to prevent this from happening. They're only talking."
(And maybe I missed some obvious information and GW did hate the R's... I've been out of the loop since very early after the arrests. So... this is all speculation based on what little I do think I know!)
But, the bottom line is what you said in your comment... odd man out or
not. As hard as it might have been for G, he had an awful lot of time to let reality set in good and deep and notify authorities.
OR~ better yet talk to his family and tell them to drop the whole idea of he'll tell police and "I've already given someone a letter to give to police in case something happens to me. Because this plan is crazy and I don't know what
my own life is worth to any of you at this point now that you know I'm not going to kill the R's."
OR~ did he just go along with it because it sounded like the most exciting hunting trip he'd ever have in his life?
We don't and can't know what he was thinking. But, I think he killed GR and at least helped to trap CRsr and may have even stood guard outside the other houses, with others, while JW had his fun. Yes... fun, imo. How exciting. What an adventure.
We do know, he told no one in authority. Legally, he's as guilty as any of them no matter what was going on in his mind from the first moment the plan was hatched until the last moment when 8 people were dead. So, I understand "dedication to committing to the murders" but the minute he chose his side... and did nothing to stop it
or drop out of the plan... he
was committed to carrying out the murders, imo.
This comment is a lot of speculation.
