Ancient Athens shows just how the people can become the mob, and how even the most enlightened cultures of their times can succumb to a suicidal collective hysteria. All due to a desire for the easy "fix" to problems. People vote for whatever short term satisfaction their collective Id wants: revenge, safety, or luxury. Eventually the processes of democracy are too slow to satisfy them, so they find a strongman who promises quick and easy solutions if only he is given the power to do them....history has yet to record this ending well.
Words to the wise.
