Assalam Alaykum
As I understand it, this is a matter of the reasoning behind judgment. The nature of judgment changes according to its context. For example, the law of the land ensures official justice through its legal system. A person serving an official punishment ought not become the victim of punishment by non-officials.
However, a person who has been witnessed by non-official individuals committing an immoral indecency that is personal in nature and does not harm anyone else ought to be judged only to a limited extent. Firstly, by maintaining distance while he commits that indecency, and secondly, by offering meaningful advice so that he may consider refraining from committing such an act, even if it has gone unpunished.
Moreover, in certain contexts, the individual himself may become worse than the witnessed immorality or crime. For example, a person may not only carry out the act but also promote it knowingly, intentionally, and persistently. Similarly, there are instances where the act of crime or immorality requires more attention than the individual or group involved. For example, in a society where slavery is a common practice and not considered wrong, the institution of slavery must be addressed as a primary issue. This does not mean that individuals are not questioned for participating in a harmful practice. Rather, the act itself must be judged first in order to eradicate it from such a society.
The reasoning behind judgment allows us to reach better conclusions about how judgment is carried out, upon whom it is carried out, by whom it is carried out, and when it is carried out. Doing so objectively, without personal agenda or grudge, allows us to get a sense of what Abu Nur stated:
"see the spirit and goodness Allah (سُبْحَانَهُ وَ تَعَالَى) created for every human being, manifesting God mercy by giving humans power, love, wealth, the five senses, strength to move, intelligence, childrens, families, bonding etc. Without anymore looking throught the body eyes; judging, looking down, envy, hatred, jealously, lust etc"
Thank you.
