Good and Evil

Is a quest for knowledge always good?

But of the tree of the knowledge of good and evil, thou shalt not eat of it: for in the day that thou eatest thereof thou shalt surely die. Genesis 2:27

Several interpretations of this passage in different denominations and religions exist.  Consider these questions representing different viewpoints.

Was the tree a bad tree?

Was the reason to not eat merely a test of obedience to just one rule and free choice?

Was the command to not eat from evil sources and the tree wholly good for man to partake?

Did the fruit have something to do with the blending of good and evil?

Did the fruit give power to evil?

An additional take is the following.

Does the meaning change if you add a word,  

Tree of self  knowledge of good and evil?

Was it really an ability to judge others, actions or things, that resulted in death?

If you judge others as good or evil do you lose a close relationship with others?

Does this interpretation fit in the context of the rest of Genesis?

Does the tree of life represent Jesus's forgiveness which would counteract the judgement of good or evil?

Does making lists of actions as good or evil take into consideration the intent behind the action?

Do the lists of good and evil actions consider special circumstances?

And let the People of the Gospel judge by what Allah has revealed therein. And whoever does not judge by what Allah has revealed - then it is those who are the defiantly disobedient. (Surah 5:47)
