A good person, moral person, righteous person, just person, no one except you would claim those persons must be sinless to qualify for those adjectives.

You started in ERROR. That's easy to do when you strain at a gnat in an attempt to show piousness.
No, no error, and all you did was list synonyms.
The word “righteous” does not appear in Genesis 23; the word “right” appears in Genesis 24 twice, once as translated from Hebrew “emeth” and properly translated “true”, and secondly as a phrase “right hand” from “yamin”; no occurrence in Genesis 25 or 26. Could you be a bit clearer on what you are referencing?
