What I mean is describing someone being kind, righteous, honest, high-hearted, etc. almost to the uttermost level.
For example, if I wished to point out the great kindness in someone's nature, could I call them "a kindness itself"? Or should it be "an epitome/image of kindness"? Or what should it be? Would the expression I'm asking for, become different if I had in mind negative traits such as meanness, toadyism, mendacity, and so on?
