In Polish the book it titled "Czas pogardy". 'Czas' means 'time' and 'pogarda' means 'contempt/disdain'. It is reference to how the WWII time is often described in Poland as 'time of contempt' for human life and other human beings.

Hatred is a little too strong. Hate is a strong feeling. 'Hot' emotion. Contempt is 'cold' and indifferent.

Contempt means (from dictionary.com)
the feeling with which a person regards anything considered mean, vile, or worthless;
This is precisely the meaning of 'pogarda'. Especially in this context of war that destroys lives and nations.

Also contempt is better then disdain because (also from dictionary.com):
contempt is disapproval tinged with disgust: to feel contempt for a weakling .
disdain is a feeling that a person or thing is beneath one's dignity and unworthy of one's notice, respect, or concern: a disdain for crooked dealing

Pogarda evokes feeling like you're not even worth enough to be hated. You just deserve to be destroyed because you are disgusting and don't deserve to live.

I would translate 'hatred' to Polish as 'nienawi??' (too stong) and 'disdain' as 'lekcewa?enie' (too weak). 'Contempt' as equivalent of 'pogarda' is just right
