Depends. Crusader has a high chance of hurting its own faction more than helping it, but it also has the potential to kill off some evils and do quite a lot.

Meanwhile, both mafia roles do a lot less for their faction, but at least don't hurt it. The mafia mostly makes use of deception and roles that support it via confusing the town even more, and these roles are certainly not as good as other mafias at doing that.

Are and  the worst mafia roles? Yes. I'd say is even worse though.
