Now this is from wiki
Goon is a member of the Mafia with no special abilities. It is the Mafia-aligned equivalent of Vanilla Townie.
This is not to say that Goons are powerless - they have access to their Mafia's factional kill and factional chat.
This clearly implies that only thing goon can do is perform factional kill.
So basically if set up has goon then I am inclined to believe that mafia do have factional kill other wise why to have this role in first place? It won't make sense just to add goon in game but don't give Mafia factional kill.
