i think this song is about being in a relationship when you've got personal issues and soul searching to do, so you can't probably give to the relationship, so all you do is take (ie, "me, i'm a thief"). i also see this in lines like where it says "i know that she's somewhere underneath but i don't know how to find her" and "i don't expect you to understand this war". so it's just about not being able to give what you take from someone
