Well what I'm saying is just in terms of what you should do as a response to something, the situations are unequal.
I agree. But why do we think they are unequal? Do we base our judgment on accurate information or on myths created by some political or religious forces?
Let me go back to my example with the clinic's visitor. Now there are two clinics with identical situation, in the clinic A the doctors decide to kill the visitor and save 4 lives, in the clinic B the doctors decide to let those 4 go. Media headlines:
"In clinic B four patients die; in clinic A only one is dead in a similar situation". "Due to heroic efforts of A's personnel 4 patient lives are saved, only one people is dead!"
How would you judge the same thing in this case, based only on these media reports? Note that they only report facts, and quite accurately. They simply omit certain little details. Now these 'little' details is what actually turns the whole thing upside down, and this is how propaganda works.
As for what Washington did, first of all, I think our modern qualifications of things as genocide is wrong.
Why do you think modern qualifications are applicable to Stalin, then? These modern qualifications were developed after WWII.
Genocide should only be called genocide, first of all, when you're attempting to purge a race on the basis of being a race.
That's what Washington did. He did not discriminate between 'warriors' and 'civilians', he simply ordered to wipe them all out. All of them, to prevent their possible future alliance with the British.
We only put as much moral condemnation on Stalin as we do because his victims were the result of him trying to maintain his personal power in office.
Not all of them, only a small minority of high officials during the 'purges' of 37-38. Happens all the time to many world leaders. They'd kill their potential competitors, ministers, generals, etc.
If you think otherwise, try to explain how the Russian peasantry (that's about 90% of all victims) would possibly threaten his 'personal power'.
Stalin, thus can be given all the blame for his situation, where a lot of Washington's blame can be diverted to territorial problems caused by America's presence in the New World and the beliefs about how wars can be carried out that were in the society.
You can equally claim that a lot of Stalin's blame can be diverted to the problems caused by Civil War, Antanta intervention, total destruction of Russian economy, the necessity of Industrialization, and the need to feed all the people involved in it.
There's plenty of excuses for Stalin. It's only a matter of which propaganda do you like better.
