The endings are just right, grim and sad as it should be. There can be no lasting happiness in a world, ravaged by capitalism in its pure, predator form. Even the "free" nomads are still the cogs in a system, raiding caravans and smuggling goods, filling the dirty and controversial niche. And yes, carma-wise V deserved death in 6 months. Man who freely chose to make a living through violence usually meets abrupt and violent death before 30s. Part of me were agreed to leave the mortal realm and step into world of digits, if not for Panam and other people, good people. V didn't deserved their love and friendship but is still obliged to respect it.
In the end V, and player too, have to decide, does he still really believes in anything at all in this world, perpetually tormented by animal part of human nature. Friendship, love, brotherhood, family, wealth, power, glory? Or better through all this away and step into new world? Perhaps, in cyberspace, with different laws defining this world, thing could be different?
