It may not show it now with only two years of records,but I am trying,and all I want is for the people I hurt to have a final sense of culpability that justice has somehow been served.上文的语境很有限，就是一个校园枪手被判刑，法官拒绝了其缩短刑期的请求。他在被判刑前说了上面的话。我看着稀里糊涂的，不知道这里的two years of records指什么，而且后面的all I want is for the people I hurt to have a final sense of culpability that justice has somehow been served也不理解，是让受害者产生culpability么？
