"The definable distinction you say does not exist is simple and readily available to anyone who wants his moral perception uncompromised by artificial constructs; for example, it could be structured by examining the relative "good" in consequences of any action in terms of bringing about future existence along various channels of creative work (such as families, other organizations, various forms of life, etc.).

Good itself is a subjective term. Different people will have differing ideas about what is "good" regarding "families, other organizations, various forms of life". Moral perception itself is an artificial construct in the literal sense that it is constructed by humans, in social environments and as individuals. Let's face it, religion and moral perception are both human inventions. And both are subjective.
