To my mind:
1) Everything in the universe was created
2) Creation is good, meaning fit for purpose: a tree is very good at being a tree, a human is good at being a human.
3) Creation was gifted with free will and choice; the God I believe in is not like the Ancient Greek / Roman pantheon, playing dice and interfering with lives.
3) All those things that a human can do that is 'evil' to another represent a perversion of what they should be used for. I need muscles to be able to stand. I can choose to use those muscles for stabbing someone or planting crops.
4) Good or Evil require choice. Humans are probably unique in that they can perceive questions of right and wrong, of good and evil.
5) God intends humans to live good and happy lives, die, and go to Heaven.
6) Humans through their choices can act in either a good or an evil fashion.
If God has given us the freedom to choose, then he has given us the freedom to choose to ignore him completely. There is no inherent knowledge in humans that there is a God, you're not born aware of God's existence. If I choose -- or even if I don't -- to be an atheist and God knows I can do this, why would he bother to punish those non-believers and those who make less-than-desirable choices? Essentially what you're saying is that God wants for us to do things in a certain fashion, but has given us the option not to, but is punishing those who don't. That's a system of coercion, more or less. Do it God's way or suffer.
If God wants humans to be able to choose and learn for themselves despite all of this and is still willing to punish those who don't live correctly, then we should probably reevaluate our idea of a "good" god into one that is a little more sadistic. The idea that God has expectations already limits our freedom of choice, and thereby goes against his original intent. In other words, if you never train a dog to stop pissing on your carpet, you can't really be too surprised or angry when it does.
If some of God's creations inconvenience us (like an earthquake) then boo hoo hoo. For God to intervene to 'save' us from the Earthquake would be for God to deny us choice. This is the fundamental thing that makes us human - the ability to choose.
How would preventing an earthquake from causing mass devastation be removing a choice? What choice do humans have in suffering these events? Those who die to hurricanes and tornadoes and volcanoes and the like don't choose to, and they certainly don't choose to have their lives altered in such a dramatic way.
Well, that's not actually true. This kind of viewpoint doesn't explain family structures or altruism. Rather, I think the nature of all life is to ensure the survival of genetic material. This is why plants reproduce, viruses infect things, and so on.Actually, it is true
. Self-preservation is kind of key to the survival of genetic material, at least to some point. If you kill yourself, obviously you can't reproduce.
Family structures are intrinsic to our society because they allow a cohesive, self-sustaining unit in order to better develop future generations of humans, thus ensuring their perpetuation.
As for altruism, this is trickier, but not all together impossible. Altruism is not found in many other species, which says to me that altruism is developed under certain conditions. In humans, we have evolved to be able to reason past a great many of our natural instincts, if we deem it necessary. We no longer have sex simply for procreation, but for recreation, for example. We have already suppressed our drive for self-preservation in a multitude of ways -- drinking, drugs, driving too fast, skydiving, unprotected sex...Teenagers are especially notorious for doing reckless activities that endanger them. There have been a few studies I've read that link altruism to the reward center of the brain, but there are even more reasonable shows of benefit, as well.
Altruism can better general living conditions in your environment, strengthen personal moral convictions, give a sense of self-righteousness, even promote altruism in return for yours (though by definition, this is not the prime motivator, but that's not to say it doesn't happen). Altruism can have practical purposes in a tribal society through creating friendly relations with others and showing good will. We show altruism to children and infants who require all of our time and resources -- though it's possible for parents to selfishly want a vessel to carry their own thoughts and beliefs on, just think of what a bastard a lot of kids are to their parents for the first 18~25 years of their life. The reward is extremely delayed and not even guaranteed. It can even backfire.
These balances are not permanent and are very changeable - think of how many millions of years this planet was an airless rock, or covered in ice, or with a greenhouse atmosphere, or ruled by dinosaurs. If God specifically created the world to be for humans, why did God waste soooo much time getting to us?
And who's to say that perfection is a stand-still? We don't know what God's idea of perfection is. No clue whatsoever, and no way of knowing. Besides, I didn't ever claim that the world was created specifically for humans. If it were, I'd start creating a polite list of changes I would suggest because what we're living on now has largely been forced to flex to accommodate us the way we want.
