It isn't my place to decide such matters, but as you have asked:
Don't go! You're just a kid! Enjoy your youth, do it for all those to whom it was denied (Draftees); marry that pretty girl you love. Trust me, you'll come back a changed man, and you will know what you truly have to lose. You need not die, be maimed or go mad. Don't let those sick "patriotic" ba****** they call officers get in your way!
