Hello LisaBObeesa's Mom. Lisa asked if it would be morally right to go back to the JWs even though you don't feel it is God's organisation. It is if you can put up with it. After all, you are going back to renew your relationship with your daughter and her children, and your friends.
As far as having to lie is concerned, there are many examples in the bible of people who had God's blessing but who had to lie.
What is morally wrong is for the organisation to put barriers up in your relationship with your daughter and grandchildren. They need you, and maybe, in time, they will also discover the truth about this organisation.
I wish you well in your efforts, and hope everything turns out right for you
