I will forever quote Metal Gear Solid for Deepthroat's Final Lines, Spoilers, so behind the Spoiler bar it goes:
"Now... in front of you, I can finally die. After Zanzibar Land, I was taken from the battle, not truly alive or truly dead. A shadow in a world of undying Light. But soon...soon, it will finally end. Snake, We're not tools for the government or anyone else. Fighting was the only thing... the ONLY thing I was good at, but... at least I always fought for what I believed in. Snake, Farewell."
