No one in this discussion except you expressed the idea that quality of a human can be expressed by a single number.

A more natural concept of overall human quality would be something like a linear combination of individual qualities in a multidimensional space.

a. Smart person - good, positive coefficient.

b. Diligent person - good, positive coefficient.

c. But works for the mob as a money launderer - bad, very high negative coefficient, probably high enough to drag the overall combination under the neutral hyperplane, so to say.

Etc. etc.
