After pressure from Konami and death threats from fans, Hideo Kojima tried to make Metal Gear Solid 4 as depressing as possible. He originally wanted Snake and Otacon to be tried for war crimes at the end of the game, but the development team protested, and it got changed to a happier ending showing them retiring (which could be interpreted as another product of Kojima's frustration).
