Amnesia: Justine Discussion Topic

[Sergiy]

Just finished Justine, and this is what I've gathered
Yes, far fetched... But this is my interpretation!

Spoiler below!

Justine is running these tests on people, and the one we played through was testing her own nature. Something along the lines of "taking the easy way, but sacrefice and innocent/important person" or do everything possible to save him.
Those people might even not be the people they're claimed to be.
The hanging body in the end is what the subject is meant to assume Justine is and seeing that there is nowhere left to go, the recordings provided some sort of comfort. Knowing that there will be no more the subject feels abandoned and is scared to face death if guilty for the deaths of those people
then then room scares the subject, and that is it, the nature of the subject has been identified.
It seems Justine's father might have died during one of these tests, such she blames herself, and finds comfort in the fact that he died for science.
