Forgiveness is not easy especially if we speak of the amnesty that happened and that still happens in Rwanda, an African country that was hit by a terrible crime – genocide in 1994. About one million people was killed in a battle for political power in the country. The battle was attended by the government of President Juvenal Habyariman, composed of representatives of the Hutu community and the Rwandan patriotic front (RPF), most of whom belong to the Tutsi community. Many may say that this is the biggest genocide since World War II in which is erased an entire entity. Members of the Hutu community began to mass killing Tutsi people. Unfortunately, even the fact that some of them were connected by a familiy bond didn't stopped Hutu people in commiting a numerous murders. Despite the horrible crime, after a while few people who managed to survive turned to forgiveness. Forgiveness to the murderers of theit families and friends. It is precisely that forgiveness is a tool for establishing spiritual peace, which is the subject of this work.
