SPOILER Question regarding Ibu's ending SPOILER

There was a lot of talk about 'Game Theory' throughout the film. I saw it as a suicide as the clothes were all neatly placed, I assume for his final wishes. I saw it as a part of the 'game' as one man's sacrifice for the greater good. Interestingly, when i was googling Game Theory there was a lot of talk about chess which was a theme throughout the movie. http://www.econlib.org/library/Enc/GameTheory.html

Interesting. I will have to watch it again. I did not get the impression of suicide at all, I just assumed it was a blood clot or something since they made a point of mentioning he was being forced out somewhat early because of medicaid (stable signs but not completely safe medically speaking).

But I do recall seeing the clothing out, with the shoes, etc. Suicide does not seem in character, and I don't see how he benefits Ben more being dead than alive.
