How does the author use the character of Visik to warn her readers in the book, Three Sisters: A Novel?

Visic chose to persecute his Jewish friends and neighbors all for the sake of a smart uniform. His character illustrates the manner in which people can be persuaded to join hate movements for nothing more than the promise of belonging and authority. The author utilizes Visik's character to warn readers that the same allure, provided by Hitler’s Nazis, can be used in the modern world to conscript young people into racist actions.
