I mean, I've seen a video of someone playing corrupted Barney and the rage made the environment dark, and the spook affected everyone, so I think it would be a good idea if the darkness was only for the rage.
Corrupted Barney Calhoun was one of my favorite bosses to play on the ff2 server, I only realized he was gone until Nutty said something about White face and said the dark bosses were removed. Similar to Arnude's post, I made this since it's kind've somewhat odd without a dark boss being in the line up of bosses we have on the server. Here's the link of the boss page I found him fromhttps://forums.alliedmods.net/showthread.php?t=285767 (I only found this page with him since I couldn't find a post with this boss in it from the guy.)
