Slaughter House-Five chapter 2

In chapter two of Slaughter House-five Billy a soldier who is against war travels back in time remebering what his life during the war was. I think he is so affected by war he has begun to become crazy. He travels back and forth in his mind with no control over it. Billy is one of those characters that are very complex. He is a soldier but he doesn't like war he is  against it, at first I believed he was like Forest Gump when he had to travel to Vietnam. He just went there because he had to not because he wanted to. He took war as something he had to do but not that he would choose to go. I think that during the whole book Billy will have many problems and challenges regarding  his lack of acceptation of war. I also connect this chapter with the trilogy of Back To The Future. In this movie Doctor Emmet Brown and his friend Marty Mcfly travel through time always trying to change things for good, but most of the time their positive intentions end up making the problem worst. Even though Billy may want to change some things of his past, it is better to let them go to try to never do those things again in the future. It is better to stop regretting and thinking "what would have been if..."or remembering  because it will never stop haunting you. Memories can be erased by good actions but Billy's problem of time will make him see things very differently than everybody else.
