Pragmatically (and very generously, in the situation) speaking, with no "positive feedback loop", no oversight, how can societies improve? Investigate the deaths and find ways improve the situation.
I'm not saying it's exactly like slavery, but with no transparency I don't want to be part of rationalising it and letting it pass unnoticed as if we didn't see it.
