Let just go to the dictionary for a brief moment, to see how it defines 'good'.

The word 'good' is listed as an adjective and as a noun.  

I could go to a restaurant and ask for a good steak ...yet, that would sound silly, as what restaurant would claim their steak is not good.  And I could ask for a good amount of broccoli with my steak ...but, when they came with the broccoli, I may feel I want a good amount more if I feel the original serving was not good enough.  Steaks are more difficult to dispute ...as it is usually ordered by ounces.  

But, enough of that ...let's look at the noun.  This is what I found on the first line: "something conforming to the moral order of the universe".

It did not say the moral order of the society ...the nation ...or even the world, it said the universe.  And that does not seem so much as an opinion that gives me freedom to choose and decide for myself.  Phrase that way, it may even seem a bit threatening to my personal views.  After all, who can I trust to be fair about what is good for the entire universe??  Certainly, somewhere there ...it is going to potentially trample my personal rights.

In the 18th Chapter, of the Gospel According to Luke, Jesus said, "No one is good ---except God alone."

In Chapter 6, of the Gospel According to John, Jesus said, "No man can come to Me, except the Father who has sent Me draw him."  And Jesus said the words He was speaking unto them were spirit and life.

I firmly believe that no one comes to Jesus unless they are drawn ...and this does not mean to me that we have no freedom to chose.  I just am saying that I believe we would have many of the religions of the world without God drawing anyone to Him, but only the truth of Jesus comes to us by God.

And I also believe we are all drawn to Him ...as Peter writes in his second letter, Chapter 3, that God would have it that none would perish, but that all would come to repentance.  Yet, though that is true of God, it is not true of us ...that we all come to repentance, as we don't.
