No, a dictator can be benevolent. What if a foreign government destroys your country, the populace is largely uneducated and you have the power to reinstitute order in to then transition to a government by and for the people? The US, under Obama, destroyed Libya, what if someone with genuine good intentions would have seized the opportunity in order to prevent what did become reality, that all the people got was a puppet government. This is partly hypothetical but my point is clear, I hope.
