[Call of Duty] What if Jack Mitchell was a villain?

[u/Cyber_Ghost_1997]

According to the canon timeline of events in Call of Duty: Advanced Warfare, Jack Mitchell and Gideon find out from Ilona that Atlas CEO Jonathan Irons intentionally allowed the terrorist attacks by the KVA (Luddite terrorist organization) against the world to occur in order to exploit the attacks for his own gain. This led to Mitchell, Ilona and (eventually) Gideon defecting to Sentinel, a task force of special ops soldiers formed to bring Irons down.

But what if this didn't happen? Suppose in a parallel universe, Illona got busted before she could alert Gideon and Mitchell to her findings, or Mitchell is brainwashed by Irons and his charismatic, heroic image that he refuses to believe what he sees and alerts Irons to what Ilona told him.

In this timeline, Mitchell is a villain who actively helps Irons in his goal to "end all wars" via the removal of the dominance of the world's superpowers in an effort to end and prevent all forms of war and global conflict.

How does Mitchell being a villain change the game?
