.. to die like a man means each drop of blood must be earned...
Some men die like lambs, some lambs die like men. To die like a man means each drop of blood must be earned by the swing of sword by sweat and exhaustion and the sting of defeat is slow and painful: you die knowing full well that you're flesh and bone and you have limits and that your limits are your weaknesses. Then your eyes close. . . To die like a lamb, is me smiling at you each day while I avoid holding your gaze for more than a second afraid you might see how bright my soul is painted in your lipstick. Dying like a lamb means I will stay put and bleed into my mouth as I bite my tongue to submission stop it from blurting and lashing out those three destructive words. . .
This is a very nicely written poem... Your use of the metapaphor of a "lamb" is ideal in the thesis you're appealing to your audience- the faults of mankind and the ultimate realization of limits, versus the slower and more painful realization of nonacceptance resulting in heartbreak... Ah, better to love than have never loved at all. Good write.
