[But wait. If scientists would have backstabbed hitler, doesn't it make them the good guys?]

That is exactly what they want you to think, US fell for the trap long ago. Google Plum Island. Corporations for example(scientific ones obviously ones with Lab experiments) another prime example of Dystopia like in movies. There are scientists that steal other peoples inventions(mainly from inventors) for granted(fame). That is how Corporations/other greedy mad scientist do it to rule the world.

Example: You think that person invented the tank, but really he gets rid of the other guy and say he/she invented it. Everyone allows he/she to do other random(suspiciously evil) expecting him/her to make something really good. Prime example of Nazi Germany.
