She has cured herself with the forerunner tech.,halsey can fix her thinking part i beleive.
Isnt it that the forerunners themselves created the flood to fight off the humans???
And one last thing,if cortana is evil,then is she on the forerunners side-i mean didact's side??
If she is then we are fucked,she has the domain and guardians plus didact and the composer,we are screwed we need 10000000 of john-117's
No not really. Cortana has simply accessed the forerunner domain. The domain was the collective sum of knowledge for all Forerunners. Thing is the domain is supposed to be destroyed. Forerunner tech is way to advanced for humans to meddle in.
2. NO. The Flood is the corrupted remains of the Precursors. Precursors were beings that made humans and forerunners as their "children" The beings could across entire galaxies/slow time etc. They were very powerful beings. At one point they decided to leave and give the mantle aka the guardianship of the galaxy to humans. However the forerunner were not happy and revolted against the precursors. most precursors let themselves be destroyed thinking that forerunners might understand that they are violent creatures and thus don't deserve the mantle. The forerunners won and took over the mantle. However some precursors escaped and turned themselves into a powder and hibernated on a ship drifting outside the galaxy. This powder got corrupted and ultimately turned into the flood. The flood infects everything because it felt betrayed by its creations. Humanity did not defend them, and forerunners killed them. It infects everyone so that it can control EVERY LIVING THING in the galaxy. That way no one will rise against them. Halo 3 makes a reference to this when the gravemind says "The sins of a father are passed down to his sons". Also a creepy thing to note is that there is no escape from the flood. Even if you are dead the flood will use up your biomass and convert you into something. All the infected creatures are still and are in extreme pain and full self aware (but they cannot control their actions). and since the flood does not die from old age, it means that once you are infected you will essentially be tortured forever.
3. Cortana is on nobody's side. She is only working for herself.
4. Considering the flood is still alive in various places it is only a matter of time before we are fucked. Also John is one of a kind. Right before the first firing of the rings when the forerunners went extinct, the librarian planted "seeds" in humanity so that when we were reborn we could finally reclaim the mantle. These seeds are genetic in nature and john is supposed to reclaim humanity's place as the guardians of the galaxy. He is our savior
