I don't think and believe that Joseph Smith is going to go to outer darkness (hell) for eternity. However, I don't think and believe that Joseph Smith is going to go to the highest degree of the Celestial Kingdom, and be married with his many wives there for eternity. There will Not be Polygamous marriages within the Kingdom of Heaven. And as solid evidence of this, I have the Scriptures to back me up on this
Here is Jacob Chapter Two, Verses 23 through 28:
Jacob 2:23-28:
[23] But the word of God burdens me because of your grosser crimes. For behold, thus saith the Lord: This people begin to wax in iniquity; they understand not the scriptures, for they seek to excuse themselves in committing whoredoms, because of the things which were written concerning David, and Solomon his son.
[24] Behold, David and Solomon truly had many wives and concubines, which thing was abominable before me, saith the Lord.
[25] Wherefore, thus saith the Lord, I have led this people forth out of the land of Jerusalem, by the power of mine arm, that I might raise up unto me a righteous branch from the fruit of the loins of Joseph.
[26] Wherefore, I the Lord God will not suffer that this people shall do like unto them of old.
[27] Wherefore, my brethren, hear me, and hearken to the word of the Lord: For there shall not any man among you have save it be one wife; and concubines he shall have none;
[28] For I, the Lord God, delight in the chastity of women. And whoredoms are an abomination before me; thus saith the Lord of Hosts.
Now, Here is Matthew Chapter 22, Verses 23-33:
23 That same day the Sadducees, who say there is no resurrection, came to him with a question. 24 "Teacher," they said, "Moses told us that if a man dies without having children, his brother must marry the widow and have children for him. 25 Now there were seven brothers among us. The first one married and died, and since he had no children, he left his wife to his brother. 26 The same thing happened to the second and third brother, right on down to the seventh. 27 Finally, the woman died. 28 Now then, at the resurrection, whose wife will she be of the seven, since all of them were married to her?"
29 Jesus replied, "You are in error because you do not know the Scriptures or the power of God. 30 At the resurrection people will neither marry nor be given in marriage; they will be like the angels in heaven. 31 But about the resurrection of the dead—have you not read what God said to you, 32 'I am the God of Abraham, the God of Isaac, and the God of Jacob'[a]? He is not the God of the dead but of the living."
33 When the crowds heard this, they were astonished at his teaching.
