My Tolkienish wit having become rusty with lack of practice, still let me try my hand at this.

So... (leaving aside all other considerations of Gandalf's 'calling' that 'ended' with the 'end' of Sauron and possible positive prohibition on assuming active role since that...) - that provided one considers death in battle of the few and 'rousing' of the rest to greater perception of the world within and without the Shire, with clearer perception of their own being/man(hobbit)hood and firmer handhold on their own lives and so on and so forth greater evil than leaving all them hobbits in slumber doing their job for them
