At what point does he become a savage, AOG? When he punches someone? You are much exercised by the death. If this man intended to cause grievous bodily harm, he would have been convicted of murder. Clearly he didn't. Sentencing someone on the basis that what they did happened, perchance, to result in a death, quite regardless of their intent, or what they could foresee, or of what was not obvious as a consequence to any bystander, real or theoretical, is no way to run a system of justice, and we never have sentenced that way.
