Mormon view of the wrong action committed by angels according to 1 Peter, 2 Peter, and Jude

I noted from an earlier question that, according to Mormons, the "Sons of God" that married "daughters of men" in Genesis 6 were human males. Based on this I had wanted to ask about three New Testament passages that seem to refer to some wrong actions committed by spirit beings or angels. The passage at 1 Peter 3:19,20 seems to say that the action happened at the time of Noah: > 19 By which also he went and preached unto the spirits in prison; 20 > Which sometime **were disobedient, when once the longsuffering of God > waited in the days of Noah**, while the ark was a preparing, wherein > few, that is, eight souls were saved by water. The passage at 2 Peter 2:4,5 seems to say pretty much the same as above, but refers to the creatures as "angels" rather than "spirits": > 4 For if God spared not the angels that sinned, but cast them down to > hell, and delivered them into chains of darkness, to be reserved unto > judgment; 5 And spared not the old world, but saved Noah the eighth > person, a preacher of righteousness, bringing in the flood upon the > world of the ungodly; And the passage in Jude 6 and 7 seems to relate their action to the fornication and "going after strange flesh" in Sodom and Gomorrah: > 6 And the angels which kept not their first estate, but left their own > habitation, he hath reserved in everlasting chains under darkness unto > the judgment of the great day. 7 Even as Sodom and Gomorrha, and the > cities about them in like manner, giving themselves over to > fornication, and going after strange flesh, are set forth for an > example, suffering the vengeance of eternal fire. Possibly related to above passages (but not part of this question) is this one in 1 Corinthians 6:3 : > Know ye not that we shall judge angels? how much more things that > pertain to this life? What wrongful action by spirit beings do these passages refer to?
