Actually both are flaming example of human backwardness. To make you understand I will give you a example I just came up while I was in the bathroom. I was thinking about the differences between those two terms and I came up with this slightly funny joke.
What is the difference between democracy and dictatorship. The difference is, Dictatorship is like a blind man running a car with 15 passenger.
Democracy is like 15 driver running one car.
Now You tell me which one do You think is better ?
Because according to me both are imperfect systems like time bombs, destined to blow up humanity along with them.
