There are various ideas of people. Considering individual characteristics and circumstances, they often have disagreements, and their disagreements sometimes deteriorate into conflicts. Some societies treat conflict as one of common consequences by disagreements and seek better solutions through their conflicts. By contrast, Bonta´s work introduces peaceful societies where people try to avoid conflicts and maintain their harmonic atmosphere by their self-restraint. These two kinds of societies´ distinctions do not mean good or bad. They have just different ideas for outcomes of conflicts under their social conditions. However, both ways raise questions through some elements of human nature: satisfied or antagonized feeling has almost no end without will of termination. If conflicts solving societies are directed to productive solutions and move up to higher steps, it is desirable. Nevertheless, human beings cannot always choose such manners since people normally seek their emotional feeling fulfillment. On the contrary, peaceful societies are dependent on social regulations with self-restraint. Yet, human beings are imperfect, and by their regulations they might not be able to appeal their conflicting situations and might not receive social justice. When their self-restraint has breakdown, their situations might be worse. Notwithstanding, it is necessary to create better societies at peace in the world. The key of resolution is respecting human rights with individuality and flexibility.
