Saying that though, doesn't make much sense for it to be Solid either. Maybe a hallucination of some kind? MGSV trailers usually feature some kind of hallucination, so maybe? I have no idea what's going on :p but my hype levels just reached new heights. Kojima said that the Phantom Pain will contradict other games, so maybe he is in fact solid, this may be another retcon.

Regading United's question of massaquering people I'm not sure, Kojima keeps saing that your choices will affect the storyline in some way or another, so maybe you will get to choose wether to use non-lethal means or go full berserker rage on them.

By the end of the game Big Boss will be seen by the world as an evil person, maybe just maybe your actions could affect say for example you chose to buthcer everybody, the public will see Big Boss as an evil maniac, however if you chose to be non lethal, the public may still see him as a terrorist,  mainly because he is still fighting against what the public will consider the "good guys"
