''Gods anger is rationally retributive. His anger is His direct, calculated response to sin.''
Actually, his 'anger' is nothing but rational. Consider this example, you know everything, you can do anything. A rock falls on your friend and kills him, do you get mad? Of course not because you could have prevented it, you allowed it to happen and you already knew thousands of years ago that it would happen so there is simply no logical reason to get mad. I understand humans have free will, so what? God created them that way and knew what would happen so again, no reason to be mad.
Also big logical inconsistencies, god wanted us to have free will but he himself killed millions.
The overwhelming majority of human suffering is human caused either via direct malevolence or indirect negligence. It could only be averted by removing human free will and making us slaves or the long hard path of gradual planetwide moral perfection.
Your example of a rock falling on someone is an exception suffering caused by a combination of human ignorance of nature (lack of awareness that a rock will fall) and general human frailty. Both of these lessor causes of suffering are self limited. They are things that we will gradually and naturally outgrow with technological progress if we can get control of our self induced harm.
Now you could argue that a loving God would set up the universe in such a way that ignorance alone would not end us. He would step in and make sure that life was not over for us when we foolishly stepped under falling rocks or when our natural bodies give out on us because we lack the knowledge to keep them functional and regenerated past the age of 80.
The Christian worldview holds that this is exactly what he has done. You just need to apologize for foolishly walking under falling rocks on a regular basis genuinely try to stop doing that and ask him to save you and he will preserve you and elevate you to a state where that ignorance and frailty do not exist. He is not just the friend who pushes you out from under the falling rock so that you can die of old age in 20 years he is the friend who brings you back to life and in such a way that falling rocks and old age will never threaten you again.
The Christian view requires faith, however, not a faith in nothingness but a faith in God. Free will necessitates honoring the choices we make in this world. If we choose to define ourselves as our own gods as independent entities apart from detached and unbeholden to God I suspect that choice would have to be honored. To do anything else would be to trample on free will.
