I don't have to pretend. A member of my family has a child with a debilitating disease, and she goes through hell while in the hospital with him. We all still love him and support her as much as we can while watching both of them go through hell. That's what most families do. I have no idea what the wandering soul parable has to do with anything that touches real lives other than to obfuscate with abstraction.

As far as being "left behind," yes, that is less ideal as we extrapolate in time the effects when compared to the group lucky enough to have first access vs those who don't. But that is also just empty moral finger wagging.

To condemn those who were able to take the first doses of antibiotics or vaccines that became available as "unethical" because there were groups in other countries that didn't have them available at the same exact time is empty of any real criticism. Maybe to deny them access is what you mean. That would be immoral.

The hope, I would think, is that this technology is allowed to grow and become more cost efficient so that, one day hopefully sooner rather than later, those "left behind" will also be able to have the choice to engage with this technology. That it is cheaper, safer, more effective, and thus able to become more widespread.

Also, note the wording of "choice." The choice to engage or not. Just like vaccines, who have plenty of superior moral fingers wagging at the perceived opposition in regards to the existence and utilization of that technology.

Do we regret my family experience? No. He is a gem that we love and care for. But if we could even just lower the possibility of it happening to others in the future? Then unequivocally, the answer is yes.
