Let's get into all the possibilities of the nawa no lynch situation
A) lynch someone kill nawa
1) we have vigi, nawa is scum, no maf rb, no witch, lynch's scum
We confirm a vigi and kill 2 evil, at most with one town killed.

2) we have vigi, nawa is scum, our lynch is town , no witch
We confirm a Vigi, lose two townies ( a mafia kill and lynch)
3) we have vigi and a witch, lynch someone
Vigi kills someone town, nawa lives, mafia kills another town, lynch hopefully nlt killing another town

4) no vigi, TDR making false claim,
We lynch someone, mafia killing another. We confirm TDR as mafia (since only 1 kill) but care that mafia might use circular logic and not kill anyone to frame TDR

I think that the odds are pretty bad.
I am open to suggestions (this is my first time to do such analyses)
