Dating from the time of World War II, Art Spiegelman's Maus tells the story of Vladek Spiegelman's life as a Holocaust survivor and the pain of his struggle to endure during those dark ages. Similarly, Thanhha Lai's Inside Out and Back Again chronicle the struggle and agony a Vietnamese family faced during the Vietnam War, how they strive to survive, and how they adapt as refugees from the war. It can be found that Art Spiegelman's book, Maus and Thanhha Lai's book, Inside Out and Back Again show important influences of both kindness and prejudice towards the creation and growth of characters in books. In these books, kindness and prejudice are described as essential characteristics in the lives of human beings; both explore different aspects of availability and prejudice. The books describe that people's predisposition or prejudice is indeed a substantial necessity for people to avoid dangerous situations and probably understand themselves and others better. Likewise, the hospitality and kindness shown in both books are portrayed differently, distorting the assumption that helpfulness is a laudable action to kindness, driven by painful ulterior motives. Both books reflect the heartbreaking truth behind human kindness and the invisible help of hunam prejudices. The important message that both authors have incorporated into their stories is how kindness is often driven by various reasons beyond sincerity. In Inside Out and Back Again, when the refugees were rescued by the Americans, joy and happiness emerged as people began to distribute food and drinks to others.

Aided by the exploration of prejudice and kindness in the characters' lives, both Hà and Vladek's experiences were told in an exceptionally human way, reflecting what human society is like in this era. These stories contain the message that sometimes there are ulterior motives invisible to people's kindness and hospitality and that people are more likely to develop kindness once they achieve their priorities. Furthermore, both stories reveal that prejudice is not necessarily negative, considering that it sometimes helps people avoid unnecessary arguments and at least motivates people to understand each other more thoroughly. In the end, these horrors that Hà and Vladek went through deserve to be valued to guide people to be more thoughtful and apprehensive in conducting their behavior in society.
