I don't know if anyone else has pointed this out already but I was researching a bit about Unit 731, a group of medical personnel who carried out medical torture, among other things, during the second Sino-Japanese War. Well, according to Wikipedia, there are some references to that whole fucked up situation in this song. I thought that was kind of interesting.

I would like to hear your rationale on this... What in the lyrics is referencing the experiments?
