I certainly think 20,000 deaths is worse than 10,000 deaths yes.
I believe there is a much greater discrepancy than 2x, between the Iraq and Afghanistan wars and ongoing drone strikes inflicting civilian casualties, and Chinese incursions into Tibet.
That's not to say I support China in their incursions into Tibet. I am very sympathetic to those who have had atrocities committed towards them.
I do think however that the scale of a crime is important, and can be compared.
With the numbers you can make meaningful comparisons. This person committed two murders, this person committed one. To suggest all atrocities are equal is weak.
Well we have completely opposing views in that case. I think if you cannot compare atrocities or crimes you are suffering from sociopathic/psychopathic tendencies (i.e. morally bankrupt) but I say that as an armchair psychologist, much like you say what you say as an armchair moralist.
I think given any number of examples you would gladly compare crimes and atrocities and quite easily state which you think is worse.
Society does this also, you can usually find it expressed in the sentencing for crimes.

So because I don't tier atrocities into more or less horrifying based on numbers and treat them all as a negative means I have "sociopathic/psychopathic tendencies"? Doesn't take much to understand you don't know what those words mean, including moralist and psychologist.
