In the context of the Book of Mormon, demons are referenced as malevolent spirits or angels subservient to the devil. They are depicted as beings that revel in destruction and wickedness, working to deceive and lead away the children of men from the path of righteousness, steering them towards acts of darkness and evil. Scripturally, those who die in a state of filthiness, unrepentant of their sins, are considered akin to the devil and his angels, fated to inherit eternal separation from God and to suffer unending torment (2 Ne. 9:16; Mosiah 26:27).
The influence of demons and their rejoicing in the misfortunes of humanity is noted particularly during times of great calamity and spiritual decay (3 Ne. 9:2). The Nephites, a civilization prevalent within the text, at one point describe themselves as surrounded by these malevolent angels, signifying their societal entanglement with sin and recognition of impending destruction due to their iniquities (Hel. 13:37).
The Book of Mormon counsel to avoid becoming like unto these beings is stern, with warnings to awaken from spiritual death and to dissolve the bonds of hell lest one become an angel to the devil, thereby suffering the second death, which is a complete and utter spiritual separation from God (Jacob 3:11; 2 Ne. 9:9). Furthermore, it is made clear that neither the devil nor his angels encourage goodness or belief in Christ, serving solely their master by persuading individuals to commit evil and forsake divine commands (Moro. 7:17).
Throughout the narrative flow of the Book of Mormon, the mention of demons serves as a cautionary underpinning, a somber reminder of the consequences of choosing a path contrary to the teachings and commandments of the Lord. Their presence and actions are given as examples of the opposition in all things, highlighting the eternal battle between good and evil (2 Ne. 2:11).
