yeah, you are right, he wouldn't have been able to comprehend what murder is at that age
it becomes philosophical, in that case, concerning responsibility, and im afraid i am no philosopher
maybe when we are considering the future of individuals we shouldn't be so concerned about the idea of setting a precedent, but still, in the broader sense, what precedent would be set if we start allowing small children to literally get away with murder?
children kill children sometimes too, there was a case in the uk where two boys around 10 tortured and killed a boy around 5, i cant recall the exact details, the emotional dynamics are completely different in that story, right? but the same precedent would apply, and i dont think anybody would feel happy with that leniancy in that emotional dynamic, so we have to be careful here before automatically being leniant, just because the victims were adults
