Ultimately, we want to increase the collective number of man-hours of existance of humans and compatible (symbiotic) lifeforms, while eliminating that which inhibits this goal.
Whatever the immediate impacts or moral reasonings for any humanitarian cause, no matter how far of a stretch you have to make, it eventually trickles down to that.
Somebody running around murdering people inhibits this goal, and this goal is better reached without said people running around murdering people. Granted, there are flaws with the system, and humans aren't omniscient. But what we do is better than not doing anything at all. Doesn't mean there aren't better ways of achieving the ultimate humanitarian goal, but those better ways certainly don't include letting murderers stick around.
Imagine if you could play god for a moment, and had a means of determining what impact the life of one person had on the longevity of others' lives. e.g. you knew that by eliminating person #1,273,490,883 that twenty other people would live for another 40 years each, on average. If you could manage the world from this vantage point, would you not work toward that ultimate humanitarian goal? Or would you just let things run its course, and not work to increase the collective life of the world?
