No life should end just because someone selfishly prioritizes certain people over others.
While that sounds good in theory, it is only theory.
The fact is, people, by nature, are greedy. We're very habitual and tend to hoard. We almost always priorities ourselves, our ideas, and those we care about over random "people". And frankly, I doubt any amount of documentaries and other such propaganda (I use that in the most non-offensive way possible) will be able to change that.
