MrDuck, this role is basically like one of either a day action cop/mort. If they vote with the group, they can find the dead and stay hidden. This would be great for, say, no reveal, or Jan setup. If dead are revealed, he can claim d1 and hammer after town all vote someone he says to vote.
Kinda interesting, but wouldn't that mostly just end up in finding out if a dead person was guilty or inno, when mostly you know anyway? Would be more interesting if they didn't know they were Rogue, thought they were real cop or something like paranoid cop.
