I suppose it depends on how one defines "good person." I can't say if the thing is actually definable at all. I don't think that any kind of objective morality exists so, for me, a "good person" is good to an individual. I think some people are "good" because they fit into my world view. Others do the same but none of us can say that our "good people" are more good for any real reason. That is my view, anyway.
Couldn't have said it better, a 'good person' is not a tangible thing someone may be a good person in my view but that is just my view, it's completely open to interpretation. One persons view doesn't change or take away from another.
Truth.
