It seems to be how people view things, it doesn't make a lot of sense to me. It's like the outrage when wealthy people get off on charges. Usually it is because they have the resources to demand the justice that should be afforded to everyone. You shouldn't be outraged at the privileged being treated fairly. You should be outraged at the many many instances of the unprivileged being treated unfairly.

Rather than making others suffer to balance things out, removing suffering on the other side has the same effect.
