Why should I think so? World there is prevailing evil and good. The prevalence of good alone is not possible. Bad also there. But we can do one thing. The density of it can be minimized. How? There are enough laws. Effective Implementation of this law helps for the diminishing of bad happenings.Man is basically an animal. His habits also like that. Killing for eating. Killing for looting. Killing for revenge. Killing for invasion. Also killing for nothing is also seen everywhere in the world. Is it man born for killing?. Sponsored war meant for what? Selling of war implement is one of the main dealing among nations. Their problems are not seen settled by talking. Leaders are emerging from the fire. Their quality is lighting fires in the so called problems. They have no conscience in poverty, unemployment and so on. In this situation, is there any possibility of possitive thinking . I dont know.
