What I think this quote is saying is that he would rather die under what he believes in than die under what he's not. Like I would rather die a in what I believe in rather than die because of something that I don't believe in. Holden would want to die for something he believes in. As A quote from outside catcher in the rye I choose a song lyric. The song is "up all night" by drake because in the chorus it seemed just like Holden he's going to do it the way he wants it everyone's opinion don't really matter and he doesnt really care, almost as if he's just given up. "I'm about whatever man F$&@ what they be talking about, They opinon doesn't count, We the only thing that matters,So we do it how we do it."
