QUOTE : Of course, human tissue completely It's unlikely that scar was composed of the same molecules. Do you think it is really appropriate to consider people to be the same entity they were seven years earlier? Because, physically, they're not. They're connected but every part has changed. Like a renovated house. It seems like after seven years you should not be liable for things you did before. Why should a man be imprisoned for a crime committed by a different physical entity? Should we expect a couple to stay married when they barely share a molecule with the people who said 'I do'? I don't think so.
