Thanks for your comments and for your confirmation of what I’ve written. Some of the research that I’ve come across indicates that there is almost a reverse hierarchy going on with current H/G groups, where the tribe/clan keeps men who get too egotistical, power-hungry, or otherwise anti-social in line. Sometimes this is with ridicule and shaming, but banishment and execution are also used, and typically it is the man’s own family who will be employed to dispatch him. It seems reasonable to believe it was similar in the past.
