In French qualité is only a positive term in common usage -- unlike English quality, which extends to "bad qualities" that the French would call défauts (more or less equivalent to "flaws").
A frequent saying in personality descriptions is il/elle a les qualités de ses défauts -- "s/he has the (good) qualities of his/her flaws". Meaning, you cannot have the positive side of a given character without showing also the negative sides specific to that character.
It is, I think, a strong point of the Western mindset (which might be traced back to the Hellenistic Christian definition of society/church as a body with different members and different functions, via the modern practice of work division for instance) that differences of personalities, qualities and roles are valued. This runs against the (also Western) tendency to individualism. If the individual were to be assessed as a self-enclosed whole, balance would be essential. But unbalanced individuals may be very helpful from a larger societal perspective.
Bottom line: at any given point in our personal evolution we are what we are, and as such we are being helpful -- although necessarily hurtful too. Judgement, including self-judgement, is pointless.
