The human mind, despite all the great wonders it imagined and built, was ultimately limited.
It's easy to imagine a bedroom. Then a house the size of ten such bedrooms. It's also possible to imagine a football stadium and put yourself in that imagination and experience that vastness. But what about an entire city? An entire country? Or even a planet?
Humans couldn't comprehend things beyond a certain scale.
They'd be sad about the unfortunate death of a young person. They'd cry for a fire in the street that killed a family. They'd mourn for the deaths of an entire street due to an irresponsible awakener's attacks. But what about the death of an entire city? Even, an entire planet?
If people were so sad about 1 death, 10 deaths, and even 100 deaths, what were their feelings about a million deaths? 100 million deaths?
Or the number of death count going up in Neptune, 3 fucking billion deaths?!
