We have asked, "Does God as the decreer and the all-powerful and all-sincere enforcer of fairness exist?".
Yes.
Based on what I see happening in the world, isn't the answer obvious?: No. There can't be such a God.
I don't accept any demonstration as something is obvious. If you claim something, you have to demonstrate it based on information.
Well, I see many blatant unfair acts have been committed in the world. I think, that's enough to prove that there is no all-powerful and all-sincere enforcer of fairness.
What blatant unfair acts have been committed, exactly?
For example, to cite some unfair acts committed by humans, some women were killed by rapists; some people who just were celebrating a holiday were killed by a truck driven by a terrorist; some students were killed by a gunman who attacked a school; some residents were buried dead by a collapsed garbage dump sloppily managed; many people of an ethnic group was slaughtered in gas chambers, . . .. Killings aren't the only problems. Some people were displaced from their hometowns by a nuclear power plant accident because of a company who lacked due ability and sense of responsibility to operate the plant safely; some children were bullied by heartless classmates and their teachers just connived at the bullyings; many women were denied due opportunities only because they were women; exquisite works of some artists weren't recognized because of tasteless, overweening critics; words of some truthsayers were just ignored because the masses were prejudiced and stubborn, . . .. Do you need more examples?
No, that isn't necessary. Do you have some examples for unfair circumstances not caused by humans?
Yes. For example, some people including children were killed by landslides, tsunami, or whatever; some people were born defective; some people were born in poor families and weren't given opportunities to study; some evil people won lotteries while good people didn't; . . .
OK. Let's clarify something: we are talking about being morally fair, which is different from being statistically fair. If a lottery is won at an equal probability for a bad person and for a good person, it's statistically fair. However, the moral fairness perceived by many people is that good people should be rewarded and bad people should be punished.
Ah, the statistical fairness and the moral fairness are incompatible. If the statistical fairness is being strictly observed, it can't happen that a person wins a lottery because his or her daily deeds have been good.
You can experiment which of the statistical fairness and the moral fairness exists.
We can let a man who saved someone's life and a man who took someone's life draw lotteries many times, and see the results. . . . I can't imagine that the good man earns more money in a statistically significant difference.
So, we will suppose that the statistical fairness, not the moral fairness, rules the world. . . . Anyone who disagrees with the supposition can do the lotteries experiment. Just we can't provide the fund. . . . Note that when someone helps someone and is helped in return because the helped one thanked the helper, it isn't God's deed, but just a result of causality. It can be perfectly explained by physical laws, and isn't any support for the existence of God as a moral being.
There are some people who claim that those harms are trials by God, but that claim is what I can never accept. While those people were already killed, what kinds of trials are they to those killed? 'trial' means that the tried one is tested on how he or she would respond to the trial, doesn't it?
According to the usual definition of the term, trial, I can't guess otherwise.
Then, what were those children buried dead under the trash of a garbage dump supposed to do? What were women killed by rapists supposed to do? They were killed without being given any option, but suffer and die!
I don't know what they mean by that claim, but the claim lacks due explanations.
And if they were trials, I can't help but say that they are extremely unfair trials! What matters is not that trials are given, but that trials are given fairly.
Trials are tests in other words, right?
I guess so.
If a test is given in a way that someone has to solve 10 problems in 1 hour and another one has to solve 100 problems in 1 minute, I don't accept such a test as being legitimate. If God has to give us tests, that's fine, but please give us fair tests!
If God is really giving trials, I think, we have to conclude that God is creating unfairness. Someone who claims that hardships are trials from God is effectively claiming his or her God is the very source of unfairness.
There is another claim that God doesn't prevent atrocious unfair human acts because God respects free wills of humans, which is another claim I can never accept. God respects rapists' free wills that they want to rape while God doesn't respect victims' free wills that they don't want to be raped? . . . It's more important to God that a hopeless villain's free will isn't disturbed than that a promising young woman is allowed to live a meaningful life? My, my!
Free wills clash with each other if free wishes aren't restricted to ones that don't crush others' free wills. Respecting free wills that crush others' free wills isn't respecting all the free wills.
God is just respecting only selfish free wills.
That's what that claim means.
If such a claim is justifiable, a teacher who didn't intervene in a bullying can say, "I didn't stop the bullying because I respected the free wills of bullies." Why not? God as the moral decreer is saying that that's the right thing to do!
I agree that it has been proved without doubt that God as the decreer and the all-powerful and all-sincere enforcer of fairness doesn't exist. In fact, such a proposition can be easily proved because a single counter-example can refute being all-powerful and all-sincere.
A vague question as "Does God exist?" can't be answered, but that doesn't mean that all the insistences on God are untouchable.
Some insistences on God aren't matters of beliefs, but are proven fallacies. Hypotheses systems that don't have contradictions inside them and with the reality are allowed, but what have contradictions are just fallacies. Choosing a hypotheses system among viable options is an opinion; persisting in fallacies isn't an opinion, but a lie.
