That is a meaningless analogy. My brother takes his own path through life and his decisions around who he socialises and mixes with will be very different to mine. So it’s unlikely that if he commits a murder I would be implicated by being related.- However if my brother and I share an interest and a talent within the very same sport and train together to improve ourselves within said sport, then it is fair to conclude that our experience, attitude and morality around training & philosophical approach will be in strong parallel.
