It would be wrong to wish someone suffering. (Although, maybe a little suffering might do some people good.) But might it be worse to desire a world (outside of Heaven) without suffering and disease? Such a world would be impossible anyway. It would be a tyranny with special sufferings of its own.
Eugenics desires to eliminate disease and suffering, or rather people who will suffer from disease. Heaven works because everyone in it is perfect. While we are here on earth, we have to contend with disease and suffering.
Imagine a world where suffering has been abolished. Where most people undergo (or have their offspring undergo) genetic treatments that will eliminate disability (or any offspring with disabilities). But, there will be some people who will resist such practices. They will have children naturally and accept any disabled babies.
They will be in a minority. They will suffer persecution in various forms. A society which thinks it has eliminated disease and disability will not welcome these inconvenient families who accept such suffering. These people who refuse to consent to unethical and sinful procedures will be penalised. There will be a culture of ostracising imperfect people. Responsible parents will have made sure they produced healthy children. Irresponsible parents will show scant regard for the common good, by tolerating unhealthy children. There won't be a culture of compassion, because people will be expected not to need any. But there will always be a few spoiling it for everyone else!.
The word "compassion" means "suffer with". A world without suffering would be a world without compassion.
Are we nearly there yet?
