When people do not believe they are accountable for their actions, (such as in public with people they don't care about, or online) their actions reflect how they would treat people lower than them. People's morals are generally a facade put on to please others. Related to that, people are comfortable with following a leader, and trying to please that person/their peers. That about covers all of your points.
