Well...I've read over everything, and I think this should be approached a different way:
Why would someone want to save Axle?
As far as I know for Town, no two people are supposed to know each other's identities or abilities. They can't discuss strategies or measures of protection to keep scum from taking them down, outside the game. It can only be deliberated in-game, before the eyes of all players, by the roles being claimed and rightly corroborated, or a certain Townie's role becoming apparent in the flow of discussion.
And as for Mafia, every scumbag knows their roles and abilities upfront. They use that knowledge to manipulate circumstances in a way that bring suspicion over Town (although all their identities are unknown). Even though they're less, by all means they have the upper advantage. And the resources to keep things balanced on their side.
Consider all that, and this:
-Apparently someone targeted Axle, but somebody saved him.
-Axle was killed, but his ability spared him.
These don't mean that Axle is scum, but someone was obviously shielding him from being taken down. It must've been a Vigilante or Serial Killer as Ninten* suggested. At any point, I'd find it hard to believe it was chance that allowed the Roleblocker to target Axle at the same time as a Vig or SK.
