The reason why i think the author decided to depict as different animals so you can notice the difference between the juwish and the hitlers army. the people that has critiqued the author is wrongfor the reason that people need to know about the past and they just think its disturbing but its life and they need to know thiers crul people in this world that can do things that you won't imagen.In the chapter 4 i dont remeber for the reason that i might of been absent but its mest up how they can do stuff like that just for the reason that they were jews.in chapter 5 "Prisoner on the Hell Planet" uses people as characters rather than animals the author used this becouse so they could see that they were the victoms so i think.i dont really know why his son called his a muder i was absent and i need to read it
