The whole premise of unification is flawed imo.
Starting from the group of all people, the strong and righteous have to separate and attract more good people to join their cause.
Re-unification with the stupid, corrupt and evil people will destroy your cause from within.
These people dont have to be inherently stupid, corrupt or evil, but they are right now for whatever reasons and they may be saved or they may be not.
Human qualities are rare in humans.
You have to grow a new group from the small amount of good people, not include everyone.
That is how cultures and societies are developing i think, not all are the same "quality" as can be clearly observed.
Purification and growth, not unification.
