>Murder is the unlawful killing of another human being without justification or valid excuse, especially the unlawful killing of another human being with malice aforethought. This state of mind may, depending upon the jurisdiction, distinguish murder from other forms of unlawful homicide, such as manslaughter.

Murder is both specifically unlawful (which is debatable in this case, even if we don't want it to be), and specifically premeditated (which it almost certainly is not). So I'd say murder is probably not accurate in common law jurisdictions, especially U.S. jurisdictions.
