You see world in black and white only. There is no black and white, there are only shades of gray. You think that those people were psychopaths from the beginning? Then you are wrong. A lot of dictators were idealists, they would do everything for their country, sometimes too much. They were loving fathers and sons. Some of them truly believed in equality for all and wanted to make their country better, life of their citizens better. I assure you, people can change a lot in their life, who knows what would you do or anyone else if you would live those people life. Sure you can deny that you would never kill anyone or hurt anyone in your life, but it's very naive. You say they are not normal, what about all those who killed people in terrorist attacks, a lot of them were by your definition "normal" before they did that, they never ever thought they would be capable to hurt any other human. They did it because environment variables changed, they have changed. You think you know what you would do in every situation in life but the truth is that no one knows until certain situations happen.

Of course their actions should be condemned but what you wrote is just wrong, a lot of them were like us until they stopped.. Most murderers do not born as murderers, they are made murderers.
