1. The central idea of this document is that the Mexican war was not justified. This can be seen in the last sentence by the speaker, "if I were to do to the Mexicans as I would have them do to me, I should let them alone". The young soldier in this text apparently battles with his conscience because of the people he had to kill during the war.
2. No, the United States was not justified in going to war with Mexico. In this passage the soldier seems unsettled with the idea of going to war. He does not find the idea reconcilable with what he read in the scriptures. He questioned the person that sent him to war and even mentioned that if the golden rule was to be followed, he had no business killing the Mexicans.
