Good afternoon, Bushwhacker.
(1) Are you looking for the word "character"? ("The mental and
moral qualities distinctive to an individual." -- The New Oxford American
Dictionary.)
(a) The three distinctive features we were talking about above constitute
(make up) Joe's character.
(2) If you wanted to use "stamp," you might say something like:
The three distinctive features we were talking about above stamp Joe
as a very responsible, intelligent, and friendly person.
(or: as a very angry, unpleasant, and lonely person.)
Have a nice day!
