Pope Paul VI's survival and the Secret of Fatima

What is the purpose of all this secrecy? Why not come out and explain it to the world?? I think we have the right to know the truth of whatever is going to happen in the future!! I don't mean to disrespect the Blessed Mother our Lady of Fatima, but why would she tell these children these terrible things that are going to happen? They were only children incapable of understanding all these things, if indeed she said anything at all!! Or is it made up by others who want to frighten the world? They say she told them a secret and to not tell anyone, okay, so why tell them anything? Like I said before I don't mean to disrespect the blessed Virgin our Mother, I love The Virgin Mary and i pray to her every day, She is our Mother in heaven after all!!
