99.999999999% of teen boys are nothing like this, IMO. I think most are quite sweet, despite their rough housing, stupid behaviors, risk taking, outbursts of anger, etc.
I believe, respectfully, that it's totally unfair to view teen boys as innately dangerous. I think about the teen boy who found a baby in the woods decades ago and finally got to meet her recently, who choked up at the memory of finding her and how that made him feel. Or the friend of Abigail Hernandez who rushed to her and grabbed her up in a joy-filled bear hug when she was found. Or my brother in law, at age 18, telling me why his best friend Miguel is so cool: "If you take everything good about humans and wrap it up into one person, that's Miguel."
Disgusting anomalies like Gaeta should not cast a shadow on the reality of teen boys as a whole, who are, I maintain, at a special, sensitive spot in a man's life, not yet burnt by the sun, not yet fully embittered by the numbers of women who will reject them for not being "cool" enough, or a bad enough "Bad boy", still aware of the magic of childhood, yet old enough to appreciate the cuteness and joy of little kids.
No, I think teen boys are really some of the sweetest people out there, in general, just overgrown puppies, and the occasional monster should not make people fear them.
