Query: Disturbing ride

The reader knows from the beginning that Col. Pyat a is disturbed and wounded character. I initially accepted this and watched him gradually lose his innocence as WW1 unfolds and darkness falls on Russia, but when he brutally seduces and attacks two young women while in a cocaine induced psychosis he became just another one of the many criminals littering the landscape. I lost all sympathy for him and closed the book. Perhaps Pyat is supposed to represent the descent into madness that occurred more generally in Europe at that time, but I'd rather examine that horror though the eyes of a morally strong character that I can continue to care about.
