When one thinks of "value judgment" in relation to personality, one is thinking about temperament?

The answer is "character".

A value judgment is a judgment of the rightness or misleading quality of something or somebody, or of the helpfulness of something or somebody, in light of an examination or other relativity. As a speculation, an esteem judgment can allude to a judgment in view of a specific arrangement of qualities or on a specific esteem system.
Character is esteem judgments of a man's good and moral conduct.
