Press space I've noticed that with a lot of facial reconstructions that they look very inhuman. I sincerely doubt that every single perceived "bad person" looked so chopped. I'm not exactly sure how they make reconstructions like these, but we have nothing of Robespierre's body. If anything, his body is in the Paris catacombs (I can make a project on my theory about that later, but that's not the point). The point is that we have no way of estimating what Robespierre looked like besides first hand accounts and paintings. I am confident that if we did a facial reconstruction of someone like Lenin (excluding the fact we know what he looks like, fun fact: you can see his preserved body in Russia), the facial reconstruction would look inaccurate. I mean, these people have made so many reconstructions and they ALL look to some degree inhuman.
The first one on the second slide comes from Pintrest so that's why I'm not a good source.
