But the Titans kept trying to attack the people in the Walls long before the fall of Wall Maria (if my theory holds up, this leave the issue of how the Shifters were unaware of the Walls and what lay within them for so long) and your idea doesn't explain why Grisha's actions back then which only hindered the Titan Shifters only to continue with his part of their apparent attack, why the Reiss were unable to control or destroy the humans from the more advanced society, or why the Shifters want to destroy the very innocent people they want to free from the Reiss' mind control. or why the Reiss turned on the Ackermans or the Asian minority, or why the Reiss were unable to control the very Titans they, created according to your theory, after they first appeared or even during the attack on Wall Maria (Grisha attacked the Reiss after the fall of Wall Maria, before which the Reiss could've driven the non-Shifter Titans back according to your theory).
