I've never once in my life met a person that sincerely thinks that each and every inhabitant of a country is evil when their leaders are.
By the way, "Iranians are evil" does not count, as it generally implies "most Iranians are evil", which, if you count it as a democracy (it is to some extent) and consider the elected leaders to be evil (a reasonable claim from a particular perspective), would be true.
