This is a key line since it captures the Wife's mix of pain, outrage, and calculation in a dangerous predicament. As she cries, "Oh, have you slain me," she lingers over her wound to the point of declaring herself dead, not merely alleging pain but making her husband's offense all the greater. Instead of taking the blow quietly, she converts her pain into public condemnation, painting herself as the victim of a crime on his part. In accusing him of being a "false thief," she is not only accusing him of violence but of being the author of a crime against something valuable that he has stolen from her, whether it is her dignity, her security, or her right in the relationship. This utilization of the term emphasizes betrayal and duplicity and identifies him as morally evil as well as physically abusive. Her words also turn the power around: whereas she is only physically attacked, she uses language to shame him and to make him take on the role of the guilty party. It's important since it highlights how the Wife employs language as a weapon; in a society where she is physically broken, she employs her voice to turn into the instrument through which she reclaims control and writes history in her own terms.
