Sometimes, people just can't sleep at night. they know too much. they strongly disagree with acts taken which lead to gross human rights violations. they do the right thing according to their workplace and keep quiet.

and they feels sick inside until they just have to do something about it, like speak out.

this state is called a "messiah complex" in some PTSD counselling therapy, its a dysfunctional state where the person takes on the guilt and responsibility of their government's actions and decides to speak out.

in other philosophies, its called doing the right thing..

but for the person involved, its about sleeping at night.
