Albus Dumbledor says It is the unknown we fear when we look upon darkness, nothing more! but i say it is more than that!
so what about the known unknown what do w know about it? let’s say supposedly Albus is right in a way ! what do you fear when someone close to you dies? what do we do when someone close to us betray us? but the question of the day is what do you fear when you are in the darknes or been betrayed by people under your nose? dumbledor suggests it is the Known Unknown of the Darkness we fear the most!
some people suggest the opposite that it is the unknown known we suffer from.i think it is in inaccurate!
