People side with the version of events they are told
Why is it so hard to grasp? Do you think people are siding with the resistance in the works if they’re presented as the bad guys? Did you side with Scar in Lion King?
I did... the elites were oppressing the hyenas for generations spewing out bullshit propaganda about it being cool to kill sentient beings because of some "circle of life" bullshit.
Sure, Scar wasn't a good leader, but toppling the Mufasa regime wasn't wrong.
