They That Have Done Good Shall Have Everlasting Life and They That Have Done Evil Shall Have Everlasting Damnation

Mormon reinforces that there are real and eternal consequences when it comes to one’s thoughts, intents and actions.

“…In the great and last day there are some who shall be cast out, yea, who shall be cast off from the presence of the Lord; Yea, who shall be consigned to a state of endless misery, fulfilling the words which say: They that have done good shall have everlasting life; and they that have done evil shall have everlasting damnation. And thus it is. Amen.” (Helaman 12:25-26)

Questions:

-If the Lord has revealed that there are three degrees of glory (and outer darkness) and that all souls will inhabit one of these degrees for all eternity after the Judgment: Why does Mormon use such stark contrast in describing only those who choose evil and those who choose good?

-Is he intentionally drawing attention to the worst and the best case in terms of the different degrees (i.e. focusing on outer darkness and the Celestial Kingdom)?
