re: Judge not, that you be not judged

For with the judgment you pronounce you will be judged, and the measure you give will be the measure you get...

I thought that this was an instruction to follow if you don't want someone to judge you and feel embarrassed. But today I came to a very scary conclusion.

If I judge someone, then some mechanism takes over, and whether I like it or not, I will be put into the situation in which I will be making exactly the same action for which I had judged someone earlier. For example:

I heard Tom talking about Pete, "I wonder why Pete is not listening to the people. He always believe he is the only one who knows the truth." When I heard that, I thought maybe he was right to some extent. But a while later, I noticed that Tom was acting exactly what Pete was doing that time, but the thing was that he didn't realize that he was doing that.

This means if you judge someone, then you will become like the very person you judged, and not only that, you will not be aware of that fact. Isn't this scary? But I don't know if I'm right. This is just an insight that just came.
