I agree with everyone who says it's just another Borg guilt trip because logically you cannot preach to everyone.
You cannot reach everyone, people are going to be missed and whenever you stop the preaching work ready for big J to bring the slaughter, innocent children of unbelievers are going to die.
It makes no logical sense for those who can't read people's minds and see exactly what they're doing with their lives the way that big J apparently can, to be held responsible for them.
To think that we fell for this ridiculous guilt trip I can only think it's because our minds were already pulverised with guilt about our normal sexual feelings, our desire for material things and our desire to be that most terrible of things - happy.
