1. Not yet, that I saw.
2. I think he's blaming the zombies and the whole catastrophe in general, along with himself.
3. I presume that its belly contained a goodly portion of Lori's body, which it seems like he'd come for (at least in part), but he couldn't even get that release. Seemed to me...
He doesn't die then, he dies later when saving Carol, and definitely sacrifices himself (though he know that, having been bit, he'll be a zombie before long, so he'd have to be put down at some point anyway).
