Apart from Hannes breaking the china tea-set in a moment of adolescent stroppiness, there is some just some rough playing around amongst Hannes' playmates, surely common to all early teenaged boys, but the only really dangerous moment is where the Asthmatic boy is made to run up the football field and back by the Hitler youth leader, and collapses halfway back, which is certainly cruel, but not exactly openly violent. One of the other boys keeps grabbing his friend in a headlock, but he isn't hurt and doesn't seem to mind him horsing around. Young boys, just like kittens and puppies and bear-cubs, always crave physical contact with each other.
