go down a road whereby suffering for humans is warranted. This is deemed as good — schopenhauer1

Right, the unknown greater good defense.

Suppose that the unknown greater good was the reason that Anya Martinez died from cancer at the age of 10 in 2018, after years of suffering.

A question is then what business people have interfering. Such an appeal to the unknown can equally mean that the efforts of doctors and medical researchers are wrong, the will of men against said greater good.

It's not entirely inconceivable... Jehovah's Witnesses and blood transfusions, Deuteronomy 1:31-36, Proverbs 3:5-6, Luke 8:50, Titus 3:6-8, ...

In 2013, Alex Radita died at the age of 15 due to complications from diabetes, weighing about 17kg. His parents intentionally left it to God; they were charged with severe neglect.

Can we say they were wrong? Well, some can and some can't.

By the assumption — an unknown greater good created/known by such a deity — Martinez' and Radita's predicaments were good. The assumption can mean that non-interference is good just the same.
