Not really that I’ve been aware of, but I’m sure what I considered to be right and just 20 years ago was different than what I consider to be right and just today. A person 20 years removed from themselves has even replaced all the cells in their body; they’re literally a completely different person. People change, and what people believe is moral varies from person to person. Certainly there have been some people throughout history who thought it was morally valid to kill others. They did so out of their own code of ethics, some have even done it in the name of religion. So it would seem we cannot all agree on what is right and what is wrong, only what is right to us, and what is wrong to us. Whether you need to put God in the decision-making process is totally up to the individual. It makes no difference to me.
