In the scriptures below, "it" refers to a group called the "Gadiantion Robbers" who work wickedness so that they can enjoy power (control) and gain (money) without interference. See if you see the powerful and rich in the verses below.
25 For it cometh to pass that whoso buildeth it up seeketh to overthrow the freedom of all lands, nations, and countries; and it bringeth to pass the destruction of all people, for it is built up by the devil, who is the father of all lies; even that same liar who beguiled our first parents, yea, even that same liar who hath caused man to commit murder from the beginning; who hath hardened the hearts of men that they have murdered the prophets, and stoned them, and cast them out from the beginning.
These people who seek power are doing the work of Satan, which rewards those who serve him lavishly but only for enough time to destroy them and take thousands to hell as well.
26 Wherefore, I, Moroni, am commanded to write these things that evil may be done away, and that the time may come that Satan may have no power upon the hearts of the children of men, but that they may be persuaded to do good continually, that they may come unto the fountain of all righteousness and be saved.
It is our responsibility to "do good continually". It will be our individual and collective righteousness that will render Satan powerless in our lives. We will do away with evil as we choose to follow Christ and elect people to positions of power over us who also follow Christ. This binds Satan and gives us Liberty from the consequences of sinful natures that we abandon. This is the only "freedom" that will bring us lasting joy.
