Given the increasing number of vaccine deaths and things only set to get worse it is unfortunately a rather safe bet to think this.

The thing is, they gamed this out and this death-toll is the likely best-case scenario with all others being way worse and The Art of War is very much a factor.

These are people willing to commit mass genocide when they think they are in control and winning, so it would be rather critical to make them think this for as long as possible so that as much as possible of their capability of way worse could be neutered as much as possible.

Given what they would do when they believe they are in control and winning, think what they would do if they didn't think this while their 'way worse' capability was largely intact..........

4-6% death toll may be horrific but given the number of people likely having access to means of creating mass-casualties and how spread out they are with all of them as individuals willing to commit genocide to save their own singular ass.

Imagine how much worse this could have been if they didn't think they were winning until the bitter end....
