Goodsir on the table.
Irving laid out with punctures to his chest.
The Netsilik family on the stones.
Hartnell's body being dragged to supper.
Fitzjames' looted corpse.

All he's had is time to dwell on each and every unforgivable thing Hickey's done. No amount of disembowelment or soul-consumption could be satisfying enough for him.
