Hmm..help me understand your thoughts better if you can..I know we have to be careful..The W's weren't at strong as the R's but they don't need money..so, if these families were both out of their leagues, who is/are the "league"? I hope this makes sense..like who would be the go between? I understand if you really can't give your thoughts, but I thought your post was very interesting.
I think KR was killed because the killers are cowards. I mean that literally. If they left him alive he would have came after them and they couldn't deal with him.
The other R's (Tony ect) doesn't strike me as being as physically aggressive as KR and CR1. The M's they may have thought could be bought off. But KR was a problem so he had to go, maybe with not as much viciousness and hatred as the others, but go nonetheless.
I think this was a case of two families being out of their league but forced together by the birth of a child.
The W's because they couldn't handle the street fighter aggression of the R's with their own show of physical strength.
The R's because they were good ole boys who would give you the shirt off their backs and had no idea the lengths some people would go for money.
