It is wrong to kill to stop killing; it is wrong to kill people; everyone has been brought up by their parents for 14 years of hard work, why should they take the lives of others... Only love can lead to world peace. Look, the protagonist is carrying a mace on his back, a packet of chili powder in his left hand, and a bucket of chili juice in his right hand; he is here to educate people around the world and let them understand the principle of loving each other!
