Yes, yes I would.
From a moral standpoint, of course I would do everything else I could first to be able to afford it. I wouldn't dare own other possessions that could be sold, for example, and still be able to justify stealing. I wouldn't be sitting on my butt at home (if I even somehow had one) and not looking for a job.
If push came to shove and I had fallen so far that I still wasn't able to afford the food to feed my family and I couldn't get food from elsewhere (like a shelter or food bank), then yes, I would steal.
...and there.."it is"
