All other creatures were created merely to provide him with food, pelts, to be tormented, exterminated. In relation to them, all people are Nazis; for the animals it is an eternal Treblinka.

In his thoughts, Herman spoke a eulogy for the mouse
who had shared a portion of her life with him and who,
because of him, had left this earth. "What do they
know--all these scholars, all these philosophers, all
the leaders of the world--about such as you? They have
convinced themselves that man, the worst transgressor
of all the species, is the crown of creation. All other
creatures were created merely to provide him with food,
pelts, to be tormented, exterminated. In relation to
them, all people are Nazis; for the animals it is an
eternal Treblinka.
