Greeting and salutations, Sunni. Nice to meet you. Hope you and yours are healthy, happy and prospering.

There is a vast difference between murdering and killing, though admittedly it is many times not observed by our 'intellectual' elite, the mass media, and etc.

Murder is taking a life without warrantable cause, which correlates to what you said, “Some killings are justified, some are not.”

You cannot murder that individual who is ferociously beating your child, but you may certainly kill, (i.e. quell), that individual, and generally, with impunity in virtually any society. Why? Because it is a universally accepted natural right that a mother may protect her young.
