There is beauty in chaos. I'm a staunch atheist and nihilist, and I've never second-guessed my life in favor of fiction. I adore life even in spite of all the horrible shit that comes with it.
Morality doesn't exist, it's not a force like gravity. It's an entirely malleable psychological construct exclusive to humans that nature does not account for, because we made it up as as a byproduct of our tribal nature. As humans are inherently social creatures edging toward globalization, it is in our best interests to support a certain kind of morality that benefits the whole.
Morality through fear or expectation of reward is immoral to me. You are not a good person just because you follow a set of rules conjured by someone else. What makes someone "moral", in my view, comes down to one thing: Treat others as you would want to be treated. That's all that's required, anything else is just masturbatory vanity to satisfy your self or impose your self on others.
There is no assigned purpose or meaning to life and there doesn't need to be, either. The only reason you even think about it is because you won a genetic lottery, the thought itself is born out of chaos. Make your own purpose, or wallow in self-imposed misery. You will either be liberated or imprisoned by it.
That about seals it.
