It removes the disincentive provided by having to try to shift a fat man from a wall, which could be a minimum of hard work but potentially dangerous if fatty fights back, but it's a similar dilemma.
I guess in that version he has the chance to warn fatty instead, so it wouldn't be certain death of 1 vs likely death of 5, but likely vs likely.
If the points would otherwise be set at random but he can choose, then he should obviously choose fatty, much to the delight of the covid thread brigade.
