Reading accounts of 731 - I'm struck by forced rapes to create more test subjects, random sadistic tests with little rigor, lots of vivisections and the occasional barbaric scientific test that actually produced a useful result. Sounds quite similar to the current US Secret Space Program and how it procures it's test subjects and the endless drive towards a new weapon that will never have a dual use spin off.
I wonder how many backers will remain unapologetic afterwards, and if they will get off scot free like the Unit 731 members did. And how pointless "gradual reform" of a system designed to this to sentient beings is.
