Edmund is one example of peace and war. He is always lying to his family. Edmund said that they were pretending and he lied to his brother and sister (41,chap.5). The only reason he said that was because the witch said it would be fun to keep it a secret between us two (36,chap.4). At the end Edmund was dieing and he turn better and was nicer.
The witch is the second example of peace and war. The witch is lying to everyone. Lucy said she calls herself the Queen of Narnia though she has no right to be the Queen at all (37-38,chap.4). She is tells fawns if you see a child bring them to me (15-16,chap.2). At the end she died and never turns good.
Mr. Tumnus is the third example of peace and war. Mr. tumnus is told what to do and try not to do it. He doing something what the witch said and starts crying and stops it (15,chap.2). He knew he was going to get hurt but he still let her go (15,chap.2). He knew her to much to kill her and he got turn to stone but aslan got him back. He got to be friends with everyone and got rid of the witch.
It is important that C.S. Lewis put it in because without it bad will stay bad and people won't be come good again. The witch would not have been killed but she let the rules to control her. Edmund became good because lucy give him something and it help him. The fawn turn good because he had a good heart and cared. Overall everyone had a chose to be at peace or war with themselves.
