The definition of a good person 

is 

someone who finds good in others.

   That is not always true, but there is a lot of truth in it. Consider how a not-so-good person is someone who is a fault-finder, and who turns friends against each other, and who scorns and taunts. Gossipers certainly are not often considered wonderful people. On the flip side, Loving one's neighbor is the second greatest commandment. Speaking well of them is a way of showing that love.
  So, indeed, there is much truth in the thought that the definition of a good person is someone who finds good in others.
