I think the song is about War
the part about dieing with a hungry mouth and all that is war torn people suffering
and the part about the lonely soldier is about a man who sees war for what it is ,as a horrible thing
his eyes are now pure and loving so he sees nothing to shoot , not his enemies not anything
and his feet still good and able to fight
feel like giving up as a personal choice not as an injury
and the part about being lonely is I think about how he is either stressed about what he has donein the war and he's locked himsel away in his mind but hes not alone because his comrads are with him
or he is done fighting and he is never alone because he cannot forget what has happened and is accompanied by his memories
