I don't know if practicing medicine without a license is a felony, but robbery is. In case of a death that occurred as a result of robbery you would probably be charged with felony murder, which does not take into account intent to commit murder, just intent to commit a felony.
Right, but that’s still “bad behavior.” In some places felony + someone dies = felony murder :: misdemeanour + someone dies = involuntary manslaughter.
I think the minimal pair is something like losing control of a car and fatally swerving into another car because:
- you were driving like a maniac and hit ice==> culpable
- you were driving prudently for the overall conditions, but hit oil spilled on a dark road (or something else unforseeable) ==> not.
