I don't think so, but lets say it is, then you add the massive missionary work you just complained about, and the genealogy and temple work to see to it that every man woman and child (not just that live now, but that ever lived) get the opportunity to accept or reject the ordinances needed to save them...Hey ya gotta admit we aren't just saying "everyone else can go to Hell", we are doing something about it, and trying to save as many as will let us.
Well, first of all, Jesus' words to the most prominent religious legalists of his day -- is that they would traverse land & sea to make them "twice the son of hell" as they were. [Yeah, I know, Mormon theology would regard even the most legalistic Pharisees as "brothers of the pre-existence"]
Otherwise, I wouldn't think that the Pharisees trying to do something about their proselyting would get Jesus' endorsement of "Hey, way to give it a college try and 'do something about spreading your religion.'"
Secondly...what do you mean "I don't think so"? What? You don't read your own Doctrine & Covenants? "These are they who received not the gospel of Christ, neither the testimony of Jesus. These are they who deny not the Holy Spirit. These are they who are thrust down to hell...These are they who suffer the vengeance of eternal fire. These are they who are cast down to hell and suffer the wrath of Almighty God..." (D&C 76)
You don't bother to read your own doctrine?
ALMA 34:33-35:". . . if ye have procrastinated the day of your repentance even until death, behold, ye have become subjected to the spirit of the devil, and he doth seal you his; therefore, the Spirit of the Lord hath withdrawn from you, and hath no place in you, and the devil hath all power over you; and this is the final state of the wicked.
Seems your doctrine is in conflict - you cannot baptise to 'save' someone where in Alma they are in the final state of the wicked
