That's not an answer to the question, dude.
Yes, I did. You just did not like the answer.
The question is illegitimate and based on a false premise.
Would you murder 100,000 COVID patients now, to keep 200,000 from dying from COVID in the future?
This entire discussion revolves around your wish that we had launched a first strike nuclear attack on Russia in 1945.
You have not explained how you know it would only kill 100k, you have not explained how you are sure it would not have sparked a global world war 3, you have not explained how you would have had the magical powers of seeing the future from 1945, and knowing how many people Stalin would kill in the future.
Finally, you have not explained how a thermonuclear attack on Russia in 1945 would have any benefit for the victims of Stalin's crimes, most of whom died in the 1930s during the Great Terror, the purges, the Gulag.
Unless one us has the magical power of seeing the future, there is no legitimate way of calculating that we should kill one million people to save ten million in the future.
The way we actually deal with mortal risks we see on the future horizon is by planning, containment, wisdom, and decisive action. Not by thermonuclear attacks or murdering COVID patients.
That's about as much as I can write about nuclear fantasies and illegitimate questions. I leave you to your thoughts of a blackened Moscow in flames.
