Setting responsibility on guardians for not having forseen or prevented that is a slippery slope, or at least leads to unintended consequences. Imagine a world where guardians will never let a kid go somewhere or do something that they don’t have 100% knowledge of, or aren’t 100% sure it’s perfectly safe. In this specific case: - you wouldn’t expect that issue at first sight - it looks fun enough to give it a try - the kid disn’t die. It truely hurts and can have long lasting damages if not treated properly, but a finger broken is not the end of the world for the kid.
