Problem is, the closest we get to see to Danzo's actions being good for the village is when Naruto and co. find out that Sai assassinated a few ninja that were a threat. Most other things we actually got to see led to bad stuff in one way or another. It would seem like Kishi planned to introduce Danzo as Konoha's "necessary evil" but them went out of his way to portray him as a bad guy (incidentally also making Hiruzen into a worse person as well).

So in a way, I agree with you - yes, there should have been dirty work that had to be done - but if look strictly at what we have in canon (even moreso in fillers), Danzo is shown to have very few redeeming qualities. I do wish we saw more of Root's operations that actually helped save the village.
