Last night we watched the documentary 'Tyson' about the boxer - it might take more attention than the kids have, as it is literally 90 mins of him talking about his life, interspersed with mostly fight footage. But it could communicate to them strongly, especially boys.
A renowned tough guy like Tyson talking about and showing emotions could surprise them. Interesting, he talks quite a lot about how motivated he was in the ring by fear, and how much of it there always had been in his life - I'm sure the same is true for many troubled adolescents.
There are no answers really given in it, but a lot of questions are posed. There's no real redemption, but there is a man trying to understand himself and his life.
