That’s ridiculous; there are millions of people raised in bad conditions who don’t do the same. Humans are inherently pro-social; original sin isn’t a thing. They are monsters.
I’m not saying that it’s especially bad conditions, more like indoctrinating conditions. It’s not like germany had very bad conditions when they started ww2 either.
But if you don’t think it’s a problem with the society and culture then the only real common denominator is ethnicity. Which kind of means that ought to be genocided when russia eventually falls.
