These are all words that are closely associated with the military. When someone is part of the military they are almost put on a pedestal that separates them from the rest and from the norm. Everyone looks up to a person in uniform and everyone respects him or her. This is how Lee felt anyway. General Robert E. Lee wanted so much to have the honor and respect and prestige that goes along with being in the military, that he was willing to be a "traitor- to his country to get it. He was willing to leave his current post in the military in the north to have a higher ranking in the Confederacy. His main reasoning, although not he only reason, honor, or at least what he thought was honor.
Lee's stance on slavery was also another reason he decided to leave the Union. In 1856 he wrote a letter to his wife about everything that he was feeling and with his thoughts about what was troubling the nation. "This is the same letter with regard to Lee's views of the institution of slavery. In regard to the sectional conflict that would lead the Southern states out of the Union "ad ultimately take Lee with them "the letter commented on outgoing president Pierce's message to Congress that set forth Lee's views about slavery and the Northern agitation against the institution. Lee was in 1856 critical of "certain people of the North- who would interfere with "the domestic institutions of the South,"" an interference he perceived as "unlawful- and "intolerant- (Nolan 30-1).
While Lee was an avid Northerner and he supported the Union wholeheartedly and wanted nothing bad to come to it, he had a stance on slavery that would suggest otherwise. It is easy to see that his personal morals and beliefs played a huge role in determining his future course of action. He said it in that letter that he felt the North's opposition to slavery was "unlawful- and "intolerant."" One can see that he thought that North should be more open-minded and that they shouldn't be trying to end something that is the livelihood of a whole section of the country.
