I have to say this is all very cliché: there's nothing in this piece that hasn't been done and done and redone a thousand times, no images that pop out, no clever turns of phrase that would make me come back twice. There doesn't even seem to be any real progression in the line of thought, the questions overlapping seemingly at random, the few threads there are popping up here and there with no coherency save the overall, very overused theme.
If you really want to make this good, then there's quite some work to do: give us readers something to catch on, something that will give a new spin on this classic stream of interrogation, or make it deeper: make us feel what lies behind it.

Line after line of question makes each question lose its impact. I agree with Jagged, and I further think that you should take maybe two or three of those questions, and really explore it in depth. I want to see some imagery in this poem; I want to see a bit more exposition, a bit more of a picture, an action, something happening somewhere, without it sounding like it's been seen before. I KNOW this is a common theme - so take it, and break it apart for us in a new tantalising, interesting way.
