To jump in or not

I've finally figured out how our world has brawls and riots. Boys can't sit back and watch another man fight. They simplt can't! My husband was wrestling with one of our sons in the living room while the others were doing homework in the office and kitchen. The boys became so engrossed with the activity in the living room, that they quickly left their seats and wanted to jump in. They felt the deep desire to gang up on Dad and help the ailing brother along. It's just like at a bar with a buddy who let his mouth get the best of him and a fight begins. Or, when there is a fight between two athletes, and the whole team jumps in. And the college universities with the out of control riots. Why is it that boys and men feel the need to help each other fight battles. Why has our wars been fought with such commroderies? Is it related to the wolf or dog packs where they have an alpha, or the leader that sets the tone, and the unrighteous one who defies the ethics of the world. My boys have been play wrestling since infancy. They wrestle at least 3 times a week. It is the constant "stick together" mentality and who is the strongest one of the pack. Right now, Dad is. But his sons are always testing their strengths against Dad and the friends of the pack are rallying alongside every step of the way. I, on the other hand, sit back and enjoy the show!
