Yar, I'm Surrounded by Very Sweet Faced Boys

Mangla is particularly famous because the experiments he conducted on twins were so garishly vile. He would amputate, like one twin's limb or infect one twin with the disease to see if it would transfer to the other in some way. At one point, he killed 14 twins in a single night by injecting their hearts with chloroform. Ye, you wouldn't call him as do or death a, though maybe you would, because it's always the aggressively normal looking guise.
