In order to witness this perfect truth, love, freedom and peace, I imagine one would have to obtain some qualifications, and that without those qualifications one would simply be unable to witness them.
So for those without such qualification, there would be no issue about wanting or not wanting to have part in that perfect existence, since without the qualification, they wouldn't have a correct understanding of what that perfection is to begin with.
You seem to think though that such qualification is not necessary, and that everyone, already in their current state, is capable of correctly understanding and witnessing perfection, but still is able to decide either for it or against it.
I think this is an absurd position, as it implies that (some) persons are evil or insane or corrupted by nature - ie. that they were already made evil, insane or corrupted. Because only an inherently evil, insane or otherwise corrupted being could witness perfection and not opt for it.
