The criminal’s view becomes as valid as that of the law-abiding citizen unless there is an objective reason for regarding life as intrinsically valuable. So the question remains as to the nature of that reason.
The only real, useful and functional source of marality is totally subjective and cannot be otherwise, which point you might discover if you could step back far enough for a moment long enough to stop the kinds of semantic errors you are wont to using, at least as far as I have seen.
As a general rule value cannot be disassociated from purpose. We can attach value to useless** things** but we cannot reasonably regard persons as valueless. It is a crime to treat people as if they don’t deserve to live. The question of what we deserve doesn’t even arise. Our life is valuable regardless of the way we live - although the value of the consequences of being alive differs greatly from one person to another. So why is life intrinsically valuable?
This again is a conflation of personalizations in my book.
The answer is that it is a source of opportunities for development, enjoyment and fulfilment. But does it cease to be valuable when there seem to be no more opportunities? If life ends at death there is no obvious reason why a person’s life shouldn’t be terminated when others decide it is no longer valuable. In other words eugenics and euthanasia are justified.
It can be seen as valuable because of “opportunities and development” from a limited viewpoint, but that’s certainly not all that there is to it, by any means, And your conclusion is not merited even if life ends at death, which is another anthropomorphism,
either way.
This is the outcome with which secularists are faced. Without Design there is no bulwark against the rejection of an individual’s right to life. If people think we don’t exist for any purpose we are at the mercy of those who may decide our life is no longer valuable. It may not always be evident even to ourselves what our value or purpose is but that doesn’t mean we have none. There is no logical stopping place on the descent from universalism - humanism - egoism - nihilism. Either everything has some ultimate value or nothing has any value whatsoever…
I won’t even try to unscramble that.
