This is my story for my Scouts (and impatient leaders) about "the bad kid" or "the annoying kid".
When I was in my troop as a Scout, there was this one knucklehead. He had at least one knife confiscated off of him every trip (as his patrol leader, it was usually by me), talked back to the older Scouts (and some leaders as well), was regularly in fistfights, had some extremely dangerous moments with fire, made the leaders absolutely crazy, and had almost no Scouting abilities whatsoever. In his third year of Scouting, we all (about 50 kids and 15 adults) went up to New York state for a week of camping in a state park. There were backpacking trips of various lengths and other adventures. One of those adventures was a 14 mile canoe trek with all of us.
Anyway, the day started in the 90s with a bright sun. Out of nowhere (the weather forcast had predicted a gorgous, hot day), we had a rain storm come through that dropped tempatures 25 degrees in a half hour, as well as soaked all of us head to toe. I was unfortunate enough to have an extremely large Scout (at least 50 pounds heavier than myself) in the front end of my canoe who froze up and would not paddle. I exhausted myself trying to get downriver, and I was freezing due to the rain and the paddling wasn't warming me up. We all made it back, crammed into the vans, and went back to camp. When we got there, I wandered back to my lean-to I was sharing with "the outcasts" of the troop (who were all kids I had had in my patrol at some point and helped along), including before mentioned knucklehead (my tent had been flooded out on a backpacking expedition, they were nice enough to make room for me in their lean-to). I was exhausted and completely out of it, and I lay down in my soaking wet clothes to sleep.
The knucklehead looked over at me, immediately realized something was wrong, and told one of the other Scouts to go find one of the leaders who was a nurse. I insisted I was fine, I was just tired. The other kids were laughing and carrying on and told him to leave me alone, I was fine. He told them to "Shut the (word deleted) up and go fine Mrs. So-and-so right now", which one of the kids, taken aback, did. He and another Scout in the bunk immediately started to get me out of my wet clothes and into dry ones.
I was, as you may have guessed, was in fairly advanced case of hypothermia, one missed by a carload of good friends (many who were also the youth leaders of the troop, many of whom became Eagle Scouts), an ER doctor who was driving the van I was in, a lean-to full of far more Scoutlike Scouts, and, in my humble opinion, a group of some of the finest Scout leaders to ever put on a uniform. The leaders came and put me into a van with heat cranked, covered me in blankets, fed me hot chocolate and soup, and sent me 800 miles home that night. Alerted to the danger by this kid, they searched the camp and found some less serious cases, which they also took care of.
It was the knucklehead, the screwup, the unscoutly Scout who figured out that something was wrong, and immediately went into action despite my own and his bunkmates arguments. If I had gone to sleep for an hour or two, who knows what would have happened?
So you simply never know.
And even those kids who do get removed, you still may have made a difference.
