I think the animation helps divorce the violence from reality. The sex certainly doesn't look all that realistic. I think the fact that it's animated, we get some leeway because of that.
Love, marriage, divorce, infidelity... life was the same here as anywhere else, wasn't? She realized now wrong she'd been; the pali wasn't a headstone and Kalaupapa wasn't a grave. It was a community like any other, bound by ties deeper than most, and people here went to their deaths as people did anywhere: with great reluctance, dragging the messy jumble of their lives behind them.
By this means we presume we have established for ever, a true and legitimate marriage between the Empirical and Rational faculty; whose fastidious and unfortunate divorce and separation hath troubled and disordered the whole race and generation of mankind.
