[W]e have a tendency to judge others according to ourselves.

There you are; human nature in action, wrongdoers, blaming everybody but themselves. We are all like that.

One of the reasons we judge each other so harshly in this world of parenting is because... we perceive anyone else who's doing anything differently than what we're doing as criticizing our choices.

it’s human nature to assume that when we see a mistake, it’s due to defects in someone else’s department, knowledge, or character,

When we set up judgments for others, they become rules that we have to play by, too. By judging others for what we don’t have or because we envy them, we sabotage our own lives far more than we ever really hurt anybody else.

You judge other people because you’re not comfortable in your own being. By judging, you find out where you stand in relation to other people. The judging mind is very divisive. It separates. Separation closes your heart.

The human capacity for guilt is such that people can always find ways to blame themselves.

When you blame others you are trying to excuse yourself. When you make excuses you can’t properly evaluate yourself. Without proper self-evaluation, failure is inevitable.

We tend to reduce everyone else to the limits of our own mental universe and begin privileging our own ethics, morality, sense of duty and even our sense of utility. All religious conflicts arose from this propensity to judge others. If we indeed must judge at all, argued Vivekananda, then it must be `according to his own ideal, and not by that of anyone else'. It was important, therefore, to learn to look at the duty of others through their own eyes and never judge the customs and observances of others through the prism of our own standards.

We are always harshest upon those foibles we see in others that we know bedevil our own natures - the ones that most gravely misbecome our self image - for blame is always easier than shame.

Too often we judge other groups by their worst examples while judging ourselves by our best intentions.

...research tells us that we judge people in areas where we're vulnerable to shame, especially picking folks who are doing worse than we're doing. If I feel good about my parenting, I have no interest in judging other people's choices. If I feel good about my body, I don't go around making fun of other people's weight or appearance. We're hard on each other because we're using each other as a launching pad out of our own perceived shaming deficiency.

When I am sharply judgmental of any other person, it's because I sense or see reflected in them some aspect of myself that I don't want to acknowledge.

In other words, I would say that the drive to blame ourselves or others comes from our inability to stay present with what is, because the sense of failure challenges us. It’s uncomfortable, unpleasant.
