In Response To: Perhaps.... *FS spoiler?* (Lone_Sniper_SG)
As stated before:
-The man HATES the SPARTAN program and Hallsey. If you hated someone, would you surround yourself with images of them? Probably not... so why would you name a folder to remind you of them?
-His program was indeed for weapons research, trying to beat Hallsey through other means.
-If he has files on a proposed SPARTAN-3 project, they're likely for the purposes of sabotaging it if it ever gets off the ground, thus furthering his own programs.
