“Sometimes
 people feel that it is wrong to judge others in any way. While it is 
true that you should not condemn others or judge them unrighteously, you
 will need to make judgments of ideas, situations, and people throughout
 your life. …
“Judgment
 is an important use of your agency and requires great care, especially 
when you make judgments about other people. All your judgments must be 
guided by righteous standards. Remember that only God, who knows each 
individual’s heart, can make final judgments of individuals (see Revelation 20:12; 3 Nephi 27:14; D&C 137:9). …
“… As
 much as you can, judge people’s situations rather than judging the 
people themselves. Whenever possible, refrain from making judgments 
until you have an adequate knowledge of the facts. Always be sensitive 
to the Holy Spirit, who can guide your decisions” (True to the Faith: A Gospel Reference [2004], 90–91).
