Sure. I'm not just going to lay down and starve. I don't advocate theft as a lifestyle, or from everyday citizens who are themselves just trying to survive (can't say I feel too bad about people that steal from robber barons, though). But I would say stealing food to avoid starving to death, is a fair move, morally.
In fact I would argue that a society that allows its own citizens to starve, especially when it doesn't have to be like that, is itself unethical and therefore not the victim in this scenario - but not everyone is going to agree with me there, so I'll just leave it at that.
