Purpose of it

Life’s questions to be pondered jinx the already tough (though it is something we all levy on ourselves) ways and perplex us. Stanley Kubrick was once asked ‘the’ question: "If life is so purposeless, do you feel that it's worth living?". He said “Yes, for those of us who manage somehow to cope with our mortality. The very meaninglessness of life forces man to create his own meaning. Children, of course, begin life with an untarnished sense of wonder, a capacity to experience total joy at something as simple as the greenness of a leaf; but as they grow older, the awareness of death and decay begins to impinge on their consciousness and subtly erode their joie de vivre, their idealism -- and their assumption of immortality. As a child matures, he sees death and pain everywhere about him, and begins to lose faith in the ultimate goodness of man. But if he's reasonably strong -- and lucky -- he can emerge from the twilight of the soul into a rebirth of life's elan. Both because of and in spite of his awareness of the meaninglessness of life, he can forge a fresh sense of purpose and affirmation. he may not recapture the same pure sense of wonder he was born with, but he can shape something far more enduring and sustaining. The most terrifying fact about the universe is not that it is hostile but that it is indifferent; but if we can come to terms with this indifference and accept the challenges of life within the boundaries of death -- however mutable man may be able to make them -- our existence as a species can have genuine meaning and fulfillment. However vast the darkness, we must supply our own light."

As a nihilist, I see no more inherent meaning in someone's death than I see in what I choose to eat for breakfast. I'm not going to deny it, that does sound fairly twisted. But it makes perfectly logical sense to me that there is no inherent meaning in life, or anything else. Things happen, or they don't happen, and in the end everyone's dead. Of course, one might argue that this allows or perhaps encourages socially unacceptable things, like murder. But just because I don't agree that there is objective meaning in the world doesn't mean that I can't appreciate subjective meaning. I do in fact have values and principles that I live by, but I live by them because they're what I feel to be right. They are created by what I'm biologically wired to feel (empathy) and what society tells me is right or wrong. I wouldn't murder (this also applies to the hypothetical "why not kill babies" scenario) because
1. I can't definitively prove it, but I feel a likelihood that others' suffering is real, tangible, and similar to my suffering in that it feels bad. I wouldn't want that suffering, and as I think of others as my rough equivalent, I treat them as I would want to be treated.
2. I feel others' pain as a result of my human empathy. As I said before, suffering feels bad.
3. I would face serious consequences afterwards. Guilt, prosecution, social rejection. This feels bad.
4. Why murder? There isn't any reason to, just as there isn't any reason to do anything else. But it feels immensely worse to murder than not murder, which is the only thing I have to replace objective reasons.

Carl Sagan said this about the same question.

The significance of our lives and our fragile planet is then determined only by our own wisdom and courage. Weare the custodians of life’s meaning. We long for a Parent to care for us, to forgive us our errors, to save us from our childish mistakes. But knowledge is preferable to ignorance. Better by far to embrace the hard truth than a reassuring fable. If we crave some cosmic purpose, then let us find ourselves a worthy goal.

So, what is it about?
