Frostbite is giving all negative hits here
-Wolves of the North
-Merchants of Halas
-Steel Warriors
-Shamen of Justice
-Rogues of the White Rose
This last hit should be a positive hit, not a negative.
I remembered repeatedly killing Frostbite to get my dark elf rogue to be able to use the bankers and trainers there, and then doing sneak turn-ins of gnoll fangs to fix the rest of the factions.
So I checked the waybackmachine to confirm-
and +Rogues of the White Rose was listed under Frostbite's entry

as well as him being listed under Rogues of the White Rose as a means to increase
