Is it possible that the more a person forgives, then the more human that person becomes?  

If a person forgives for the other person’s benefit and because forgiveness is good in and of itself, then the forgiver is practicing forgiveness as a moral virtue.  If a person forgives with the principle of love (in service to others), then this person is practicing forgiveness on a very high level.  I do think, in these cases, that the forgiver is bringing out some of the very best that humanity has to offer.
