I doubt I will ever be capable of thinking of the lives of those who, e.g., commit attrocities as sacred, rather than a scourge and a blight upon our species
I think I understand a possible kernel that perhaps are getting at here (?), that if for example, maybe Hitler had thought this way, then there'd be no reason for anyone else to have ever come to think of him as a monster in the first place, because he would've never committed atrocities?
But I don't think humans will ever evolve to that point, or at least not in the next 500 or 1000 years (if we aren't extinct before then), our trajectory thusfar over hundreds of thousands or millions of years of evolution of hominids in general has not shown muc behavioral progress at all, e.g., we still have religion (fantasy / faith) alongside science (reality / fact), which in turn continues to remain an impetus for tribal / ethnonationalist / ethnosectarian borders and ongoing land conquest even in the 21st century, so that a given religion can spread and impose itself on others whether they want it or not ... this seems to be an eternal facet of human nature so I don't know how to reconcile it with an ideal of a borderless world ... like what point in history of one group's colonialism or another's do we select as the time that we accept these are the borders from here on out, that we neither seek to continue expansion nor to seek repatriation to previous settlers (who ultimately migrated out of Africa eons ago) so that we can at least have some civil stability until such a time when borders and tribes may finally disappear altogher in a true era of enlightenment (or at least a scientific acknowledgement that this is oen planet and the atmosphere doesn't give two f*cks about arbitrary national borders drawn out by a minority species, or how many tribes that species has conjured into existence)? This applies to the Levant, the Maghreb, all of the New World, etc. At this point in time it really is amounting to a splitting of hairs as to who was where first, it really doesn't solve anything for generations actually alive today.
The competing tribalisms and their artifacts like myriad languages and alphabets continue to latch onto things like who was where first and continues to drive conflict. Even if there was no who-was-here-first conflict, the artifacts like myriad competing languages on a single planet (imagine Earth having to address any intersteller civilization — what language do we use as a united planet speaking to another planet?!?) continue to directly be a barrier to something as basic and necessary as communication, and are perhaps also a subtle butterfly effect genesis of derivative conflict, which maybe leads to the next Hitler du jour, and the continuing quandary of whether to view that person as a monster, or to view their life as sacred too. But we haven't solved the problems that would make that question moot.
(I hate writing long comments like this on someone else's post, maybe I should make it a post instead, and link to it here, after a certain word count)
