Mosiah Chapter 29

29:5-39 - "...and he also unfolded unto them all the disadvantages they labored under, by having an unrighteous king to rule over them..."
King Mosiah outlined lot of good points about government, but the key, in my opinion, really comes in verse 35, where he unfolds the disadvantages.
When we go to make a decision, we need to look at all the sides of the decision - the advantages and the disadvantages.  Then we are more able to make an informed decision, and then take the decision to the Lord for confirmation.  This is what is meant by the phrase, "Study it out in your mind (D&C 9:8-9).


29:12-13 - "...for the judgments of God are always just, but the judgments of man are not always just..."
If we could always have righteous people to lead us, then a King is the perfect choice.  That's somewhat how it will be like with the Lord and the Millennium.  Granted, the hierarchy will also include leaders and reporting back, I'm sure...but it all comes back to Christ, who accomplished the atonement for us.
When judging others...we really should forgive them and let God do the judging as much as possible.  There are situations where we are still called upon to judge (such as a judge in Court, or a Bishop / church leader).  However, if somebody has wronged us personally, we should forgive and leave the judgment to those who should do the judging.


29:19-20 - "...and were it not for the interposition of their all-wise Creator, and this because of their sincere repentance, they must unavoidably remain in bondage until now..."
The Lord had brought them out of bondage because they repented.  Until we repent, we will remain in our own personal bondage.  We should repent as quickly as possible and stop wallowing in that bondage.
