Well no, it's not a statement of faith, but it is a statement that presupposes you're familiar with human psychology.
I've got a number of other comments here at this point that cite sources which explain things better than I'll ever be able to, if you're actually curious, I recommend you read those sources (and others, "are people good?" is a fairly well trod area of psychology, and indeed philosophy).
