I judge others and am not jealous nor arrogant. There are many ways to judge. There are postive ways we judge people, such as being dan l’kaf zchus, or we judge unfavorable behaviour so that we do not accept such behaviour. Judging in a negative way as to why people do things that are not our business or is not wrong just different, is bad.
We judge people in our daily interactions with them, whether we realize it or not. It is simply human behaviour.
