Life is not perfectly crafted for life by immutable laws. There is a lot of horrible and very poor aspects to existence.
What if life wasn't meant to be perfect? What if the purpose of crafting of life by immutable laws are to make sure that life is just sufficiently crafted for make survival [and/or even thriving] possible?
And how can we know that these perceptual horrible and poor aspects of existence aren't designed for specific purpose? Let's take human's inherent short-sightedness, for example. I don't know about others, but I think it's a poor aspect of our being. But what if this was done purposefully so to put human's foot on fire leading them to exert themselves in making tools that'll make up for that short-coming? Take human irrationality for example as well. Poor aspect, in my humble opinion. But what if this was purposefully designed to keep humans humble and grounded to the reality that they are far from being perfect, and they make mistakes [out of irrationality], and they'll keep seeking ways to rectify their affairs rather than becoming arrogant and stubborn, thinking they can't make mistakes?
Life is not governed by moral laws either.
I don't think I agree with the statement there are no moral laws. I've personally witnessed the law of karma [and many other spiritual laws] play out right in front of my eyes over and over again. So have many others. But these are just anecdotes. Anecdotes aren't evidence.
However, even if I agree with you here, I'd like to point out that we don't know this either. Pretty much like we don't know if God truly exists. For that, we would need to be omniscient to know for sure that moral laws are absent in reality. Think about it this way --- Suppose I go back in times 6000 years ago, and talk about black holes to the people who don't have any knowledge about black holes, they'd say --- There are no black holes. That's not true now, is it? They are making an assumption. We now have the necessary means to observe black holes. Same can be applied to the moral laws. Maybe there are morals laws subliminally governing our life, we just don't know about them yet.
Is who even the right question?
I would think so. [If we assume that there are spiritual laws in place] That's because it usually requires a sentient, intelligent, creative, efficient agent to achieve the end result of [for example] karma with perfect precision.
Then the who is not a perfect being who comes up with perfect laws.
According to our limited thinking. Same applies to atheists as well. We can't possibly judge God's character, thinking, wisdom when we can't even accurately get far simpler things right [like many unsolved earthly phenomenas, psychology of certain individuals etc.]. God may be perfect, He may seem imperfect because of our misapprehension of reality.
