I want to believe that our future will be more tolerant and humane.
I'm sure that now is a more humane time than 300 years ago.
300 years ago there was a more humane time than 700 years ago.
700 years ago there was a more humane time than 1500 years ago.

And there is no doubt that the future will be better. The main thing is that people draw conclusions from the past and do not spoil anything.
