If it is improper for us to pronounce someone whose life showed no trace of living faith in Jesus Christ to be certainly damned (as I believe it is), it is equally improper to pronounce such a person saved.
We all do the best we can in this life, and hope for mercy when we err. I see no reason to not hope that all have a chance. 'nuff said on my part.
