i make role from people ideas and this was one but it has no radar.when other dev make roles mostly of there role ideas .as well the devil and the traitor who whould do that are have not had any thinking about the innocents

Ok, here a little review:
The Devil can only see Traitor-Traitors--> That means, he will not see special Traitors (Hitman, Executioner,...)
Also, I would like to know, why you thought, this would be a good role (This is not meant to be offensive, even though it sounds like it!! pls don't misunderstand), because if there is a Devil in the round and he can instantly call out all the Traitors and the Traitors can call him out, which would call out everyone and it may end the round prematurely because of that...
