Blue wouldn't be a revive by town mainly cause of his janitored role. The fact that he was might be either his own ability, a passive one, or scum. If a scummate revived him, it doesn't really not help them. Again, Blue was janitored, so as scum the revival there would slightly work in their favor since there's nothing confirming him as bad.
I mean if Blue is confirmed scum here, then by extension the Decim role is scum.
