I’m pretty worried, actually, about your assertion «someone actually has to sit and think», my contention is exactly opposite that the Hostel Franchise Friendly mentioned by The League, supra, will not have that realization, but will have the full adrenal rush.

Nowhere is it said more poetically than in Proverbs 1:11-16:

11 If they say, Come with us, let us lay wait for blood, let us lurk privily for the innocent without cause:
12Let us swallow them up alive as the grave; and whole, as those that go down into the pit:
13We shall find all precious substance, we shall fill our houses with spoil:
14Cast in thy lot among us; let us all have one purse:
15My son, walk not thou in the way with them; refrain thy foot from their path:
16For their feet run to evil, and make haste to shed blood.

I should amend this to say:

“Come with us, let us gorge on Cheetos and watch snuff footage, let us lurk privily for others deaths without thought: Let us our eyes swallow up their cessation and experience with them the voyage into that pit: let us find there the nothingness that our empty souls so luck for, cast in thy lot among us, let us have one voyage into the morbid: My son, walk not thou in the way with them; refrain they from their path: For their feet run to evil, and rejoice in blood shed.”

someone actually has to sit and think ‘that was a real life that was just ended; that person surely had future plans and hopes that are irretrievably scrapped, will never have the chance to marry / pursue that hobby / watch their kids grow old, etc.’ and also consider the secondary effect that death has on the people who knew the deceased, before any emotional impact (and revulsion) can be felt.

without that rumination it probably has the same effect as what they’ve seen expertly mimicked at the local cinema. that is, to say, none.

I don’t believe for a moment that the same audiences that made the Saw movies and Hostel a phenomenon won’t show up for live deaths.
