Can a dictator be nice

Yes. Most dictators are normal human beings once politics are removed. People who are close confidants of a number of dictators remember them fondly. If the question is asking whether or not dictators can have a positive reputation and be viewed as friendly by their citizenry, the answer is also: Yes. King Mohamed VI of Morocco, former President Habib Bourguiba of Tunisia, and former Prime Minister Lee Kwan Yew of Singapore all have such a reputation.
