Well the easy answer is that they can't sue anyone. While humans may be willing to be tested, the family of said person may object to the issue and claim that the person was acting on partial insanity, thus allowing the family to sue the company Dr. Grimm.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
