Wrong, you seem to be hung up on your own definition of reality and what is good and evil. Good is what moves all creation forward and evil is contrary to that. You speak of murder and, yes, that is evil so far as it is done as an attempt to usurp the authority of God and that is what makes it wrong. Only God knows how to keep things rolling forward and no man has the ability to deny another his or her life or the right to try, only the ability to cut temporal life short and, unless your actions are in keeping with the guidelines the Lord has set, your actions are evil and you shall be judged for it.
Let me ask you this question. "What makes God...well...God?" I believe that it is because all creation willingly bows to His will (extremely simplistic way to put it but you get the idea) Now, why do you suppose that is? I think it is because He acts with absolute equity and justice and has proven himself worthy of that level of respect. Now, what can disrupt that flow of growth - namely free thinking individuals who think they have it all figured out, as did Lucifer, and act in a manner contrary to the forward organization of all creation, so, acting in support of the forward motion of organized creation is, simply put, keeping the commandments of God, anything less is less and if you are not moving forward you are moving backward...If you are not being good you are being something else.
Mankind is hung up on the concept of reality, not having a full knowledge of what reality really is. Actions are called good or evil but the concept of good or evil is subjective to the standards that all creation has set to keep things moving forward placing God at the helm because He has proven worthy to be there. In order for God to be evil He would have to stop the forward progression of all creation and that would effectively end all creation.
When a man murders he is not changing anything other than to unjustly dispatch another into the next life and thusly subjecting himself to the demands of justice. He is choosing to attempt to interfere with the rights of others to move forward in the realms wherein God has placed them. God can and will make reservations for those who are so unjustly treated by their brethren while those wicked brethren (murderers) have simply put themselves beyond the ability to ever be at the helm of creation.
It is a perfect plan wherein all creation can move forward while perfecting those who are the children of God to one day inherit all that He has. Not all will make it because not all will prove that they can be trusted with such power.
As I said before, evil is the absence of good just as darkness is the absence of light. In fine, a person who chooses to do evil is simply attempting to prevent the forward motion of all creation which is dependent upon the principles of justice. Just as darkness is nothing, literally, and nothing is the absence of something, in this case light, evil is only a condition that lacks anything good.
