I'm saying, if it turns out that evnafets is indeed a loyalist peasent, then there isn't a better situation that the rebels could have gotten themselves in since by that point, even if they have 4 rebel peasents and just 2 rebel nobles which is your best case scenario, you'd be giving them peasent lynch control assuming 6 peasents remain.
If they gain control of the peasent lynch wagon, they just have to lynch the emperor tommorrow with their peasent lynch control and put you on the throne to win.
Basically, your plan now gives you and the rebels the perfect opportunity to win if evnafets turns out to be loyalist peasent as well. On the other hand, if instead we target a noble or 2 today, even if neither turns out to be a rebel, we're still in with a chance as the emperor's vote counts as 3 and the rebels will most liekly still not have peasent lynch control.
Basically, it's a matter of putting your eggs all in one basket hoping that evnafets turns out to be a rebel and a peasent or hedging your bets and targetting suspected noble rebels which wouldn't lose the loyalist the game even if your suspiscions turn out to be wrong.
