I admit that my question is quite useless in terms of practical philosophy or ethics, but I came to wonder how ethics will be changed if the life of human beings or further, the life of every organisms were eternal. What I mean by "eternal" may not be so rigorous, but let's say that the body of organisms can be regenerated as soon as they get destroyed. Also, let's say that organisms do not die due to their age and also do not get any pain when they get injured physically.
Why I came to this kind of imagination is because I thought that contemporary moral rules or principles in normative ethics are hardly dependent on the death, pain, and things related with finite lifespan. Thus, I thought that moral principles will be changed enormously if there were some kind of possible world where the concept of "death" do not exist at all. However, if people have emotion, then I think some kind of moral principles related to emotions may still exist.
I wonder if philosophical argument to answer my question is possible or if their already exist some kind of related philosophical document. I have an intuition that this matter is somehow related to the problem of meta-ethics and moral realism but I cannot grasp how it can be related in detail. If my question lacks philosophical importance then any advice about how the question can be improved are of welcome.
- I add the condition that there is nothing like scarcity of resources in this possible world. In other words, people can suffice their need as much as they can. Maybe it would be easy to imagine some kind of heaven which Christians mention. However, I think there still remains the problem which roots from the relationship between people. I have hardship in developing my ideas formally.
