Those make good reasons under most circumstances, especially in civilized societies.
In other societies, the conditions can be the opposite. In societies without an effective police force, the norm is that an honor culture develops, where avenging a murder with another murder is not only a right but in fact a duty.
In such societies, the first murder can actually be considered heroic, if there is no effective retribution, and the second murder is essentially always heroic.
Morality is much more dependant on our society than many think. If anarchist actually get their way, an honor society will emerge from the chaos fairly quickly.
(Examples: Current clan societies, such as northern Pakistan, Afghanistan, histoircal clan societies (vikings etc), hunter-gatherers, criminal gangs, etc,etc).
