Why evil/suffering exist if God exists—is a wrong question

A person chooses to act in a way that makes him affected with all sorts of diseases and suffering, and then it is wrong for him to ask “Why do I fall sick if hospitals exist?”

Humans choose to act in a way that earth is filled with problems and suffering. They have not yet experimented the very solution they know:  One-World-Government which can remove all wars/conflicts and convert this earth into a paradise, many have not stopped their inhumane treatment to fellow humans, they have not stopped all sorts of killing, they have not reversed all the harm done to the planet, they have not abandoned life-styles that invite diseases, they have not adopted life-style of some who never fall sick ... etc. These acts are at the root of all evil/suffering.

If evil/suffering exists even after adopting such solutions of global proportion, then only they can take up the question “Why evil/suffering exists if God exists?
