I am not sure if good exists,
i got different Ideas I can't decide, first of all I belive in Nietzsche who says there are no good deeds only selfish, then I am a utilitariaist and belive good is what is useful, the third thing is I am not through with that whole predestiantion stuff and I am all in all rather indolent
so I can't decide, but I have an Idea what you are talking about when you say good since my parents probably considered the same good.
And now I answered the wquestion I am not sure if good exists from my point of view now I'd rather say no it doesn't.
