Angels are a different created order then man, and it is given to man to one day judge angels, so clearly mankind, who were created a little lower than God, is required to use judgement.
One of the most misused verses is "Judge not lest you be judged", without going on to read the full text,"first remove the beam in your own eye, that you may see more clearly".
If, and as, we mature, and we see a wrong done we immediately reflect on how we ourselves may learn and avoid such and move with compassion on the situation.
