Guys!!
These words are not talking about different people's perspectives of cheif...they are in chronological order telling the story of John!
first he was a SON, then he was ABDUCTED, then he was a VICTIM of the unsc spartan program, and and ORPHAN. He then moved through the ranks starting as a RECRUIT, becoming a SOLDIER, and humanity's WARRIOR. He became the ALLY of the arbiter, and the HERO of the universe when he stoped truth from firing the rings, and cortana's SAVIOR when her rescued her from the flood. Now he must become a TRAITOR to the unsc to find out the #truth.
At least that is my theory about it all.
