That's an extreme example, but automotive suicides that kill other passengers, drivers, or pedestrians fall into the same category. Consider also deaths from accidents involving drunk driving or fatigue -- thousands of motorists take to the roads every day modified in one manner or another that reduces their driving aptitude.

Also, while it may be correct to say that computers don't "fear death", there's no reason that "risk to self" can't be part of the criteria for decision making by an autonomous system.
