Although, thinking about this again.
A mislynch on Day 1 and double kill on night 1 would be game over right?
So maybe it is better to no lynch on day 1?
It wouldn't be game over and the kills would have to succeed. If they did, as town still has even votes and ties are broken at random, we have a chance there as well as with towns own vig abilities if they haven't been used.
So you think its more likely that mafia holds on to both vig shots on night 1, wait until after a mislynch on day 2, assuming its no lynch on day 1. That makes it 2v2 with not much info for town to go on. But it would mean from there on out, only town has the ability to night kill.
