Enjoyed the film, although was about 20mins too long. question
If Waller red buttoned erbody wouldn’t starro have obviously controlled everyone on the island and then eventually go to America but now even bigger and more powerful?
Yeah, Idris knew that Waller and them didn't understand the danger so that's why he turned around.
In universe tho I'm sure the Justice League would've handled it but this a suicide squad film not a JL film.
