My thoughts
In quantum mechanics, anything that has ever come into contact with anything else is said to be forever "tethered" to it. Two electroncs, once together, now on opposite ends of the universe: if one undergoes a change it will cause a change in the other electron instantaneously, they're tethered in non-locality (space doesn't really exist). So if everything arose from the big bang, everything is tethered with... well, everything! We're all one dynamic equation where every human, animal, plant, stone, atom is constantly affecting every other human, animal, plant, stone, atom.
Allowing or not allowing others to suffer is a a social construct, and in the grander scheme of things, merely the effect of our DNA's coding. Early on in human evolution we needed to either fight for our lives or run away, this was programmed by our DNA and accounts for our survival. These days, with the exception of "da ghetto", this coding is not really required, but we haven't had long enough to evolve "out" of that coding. It still keeps people alive more than it kills (just hurting someone doesn't count in an evolutionary sense unfortunately). Fortunately for us though, we're living in an age where we can consciously "reprogram" our behavior, and to hell with what our DNA first told us. People just need to have a reason, to think about such things. Your movie certainly helps people do that. Good job, and I'm looking forward to the next one!
