You think because the names you listed were leaders of their countries doesn’t make them part of a greater evil? No one person commits atrocities alone; there must be some backing.
One single name doesn’t get to make decisions… There must be a greater body at play. There has to be support of some sort, otherwise the people would have just said no, and killed that person.
My point wasn’t that single people can’t be bad, or do bad things, but ultimately to perform terrible acts at scale it requires buy-in from other people. Without support, whether it be through fear, coercion, or otherwise, it’s nothing more than intrusive thoughts.
Hitler was a bad dude but it took a concerted effort by who knows how many people in order to make the sick stuff that happened a reality.
All the names he listed were indeed bad dudes, but I feel saying Kissinger stands out because he had the support of the government while the others just killed millions by themselves is not a fair assessment of what transpired.
