Is GOD the creator of all things or just some?

John 1:1-3 In the beginning was the Word, and the Word was with GOD, and the Word was GOD. He was with GOD in the beginning.
Through Him all things were made; without Him nothing was made that has been made.
Isaiah 45:7 I form the light, and create darkness: I make peace, and create evil: I the LORD do all these things.

Actually a better translation for the original text would be " In the beginning the Word was, and the Word was with GOD, and the Word was GOD."
The reason is that GOD didn't just exist in the beginning, He existed BEFORE the beginning. The Word was already there before the beginning. The Word is speaking of JESUS who has always been with GOD and is GOD.

Here it tells us that GOD made All things not just some, that means He made evil too, according to His purpose. What was His purpose? To share His great love.

So then comes Gen 1:26 Then GOD said, "Let Us make man in Our image, in Our likeness," in order to share His great love. Because He loved us, He created a wonderous world for us to live in.

However He did not want just robots or puppets who would respond on cue, so He gave us a free will to be able to choose Him. But in order to choose Him, He had to make another choice other than Himself, so He made evil, in order that we could see Him in His glory. (how can you see if something is pure if you have never seen unpure?)

JESUS said in John 8:44 that Satan, the devil, was a murderer from the beginning, not holding to the truth, for there is no truth in him. When he lies, he speaks his native language, for he is a liar and the father of lies. Therefore Satan couldn't have been created good and beautiful or JESUS would be lying. Satan was created evil in order that we might see the beauty, majesty, glory, and purity of GOD. When all opportunity has been given by GOD to draw all who will, to repentance and salvation through CHRIST, then Satan and all evil will be cast into Hell and Hell and all its inhabitants will be destroyed, leaving GOD ALMIGHTY and His sanctified people to worship Him for eternity.

What is the purpose of angels?
GOD created the angels to serve His purpose in bringing us to the fulfillment of His divine purpose for us. Servants are not asked to serve, They are commanded. Some angels are warriors, some are messengers, some helpers and protectors. Even Satan is a servant and cannot do anything, even to the smallest measurement that GOD will not tolerate. GOD only tolerates evil for as long as it suits His purpose to bring people to repentance. GOD has created Satan and given him an exact amount of power and ability for the purpose of GOD alone.

Satan is so prideful and pompus that he thinks that he can some how defeat GOD, so he tries, but he will fail completely. JESUS says, He won't lose one, no not one. This is a good example of Romans 8:28, And we know that GOD causes everything to work together for the good of those who love GOD and are called according to His purpose for them.

GOD did give the angels one opportunity to choose who they would serve and some did choose to serve Satan. After that one choice, they are commanded not asked. The remaining angels worship GOD along with all the rest of creation, but they were not created to worship but to serve and are obedient to Him. Because of the choice He gave them, God made the angels voluntary servants- not slaves. God has many servants, but no slaves. But their choice was to surrender their will to God, so they always obey Him, and they enjoy wonderful rewards. Those who chose to follow Satan found out that he is a liar, and that choice threw them into a cruel dominion where there is no reward, no mercy, no peace, but only fear and grief with no hope. The Word has a lot to say about this as part of the warning that we need to choose to serve the loving God.

God's offers to us, always call for a willing response which results in peace and joy. Satan's words are always deceptive and false, resulting in fear, grief, and misery. His promises of good things are lies, and they drag people into slavery and death.

We are the only ones GOD created for the purpose of worship and it is to us that the opportunity to serve is given as well as worship. We have to choose to worship and to serve with every single decision we make. However there is one choice we only have to make once. That is the acceptance of the gift of Salvation through the death, burial and resurrection of JESUS CHRIST our LORD. Once we truly accept that gift we can not undo it by our own actions. (see post "Do we have eternal salvation? Psalm 139)

Why did GOD question Adam and Eve and not the serpent?

A question is always an opportunity to change and do what is right. GOD asked Adam and Eve four questions. He gave them four opportunities to repent for their sin. I believe this is another picture of salvation in CHRIST. The number four always represents CHRIST. CHRIST's sole purpose was to give us rescue from death and salvation from sin.

GOD did not asked the serpent any questions. He was really speaking to Satan who had taken on the body of the serpent. GOD did not give Satan an opportunity to repent, because He knows that Satan is 100% evil and cannot repent. Since GOD knows this, that is why He does not mourn Satan.
