I'm pretty sure that Obama is a Democrat, not a socialist. Socialists, just as any other non-democrat/non-republican party are pretty much hopeless in this country the way it is. And, yes, I guess becoming a socialism would be terrible. I constantly read about the horrible things going on in Norway and Sweden.
As for the Nazi Nurses, I think it's really hard to understand what was going on. At that time, there was a national party that had the support of all the people. It seems similar in America sometimes, as there seems to be a feeling of "If you're against the war in Iraq, you're unpatriotic/a terrorist". There is a lot of "us vs them" sentiments here. The "Religious Right" are siding with the Republicans. The Democrats are all "liberals wanting everyone to have an abortion". Children are being suspended from kindergarten for sexual harassment. Our prisons are incredibly overcrowded, and our sanctioned murders (death penalty) is also astonishing.
Everyone does things they don't like. People drive, despite knowing that car accidents kill thousands of people, and CO2 is bad for the environment. They eat fast food/red meat despite knowing it is bad for their health, and grazing farms are also destructive to the environment (and kill people). We don't consider our actions to be the same, because the victims don't have names.
I'm not sure I see a big difference in the way some countries treat others. The US military, for instance, has probably killed more civilians in our war than the Nazi nurses did. Israel is currently starving an entire population of people, and being fully supported by their countrymen. Zimbabwe and Sudan are having issues where killing civilians by other civilians (or military) is becoming a way of life. I don't see the Nazi nurses doing anything different than any other group of killers with a herd mentality.
The nurses, given a chance to look back upon their lives, are probably horrified by what they did. There are situations in most people's lives where they feel forced to do something they don't support. Often times it's peer pressure. Rarely, it will be to do something to kill or save someone's life. The Euthanasia was a terrible thing, but so is being forced to keep someone who is dying, and in pain alive (while Coding). I wonder how many people, put into that situation, would act differently. Consider that, about none of the nurses then did. I wonder if humanity has changed that much.
Wow, that was long, and probably had no clear points.
