This is a WONderful topic and goes deeper than most people are willing to take it, HOWEVER, understanding the full mystery and plan of GOD is MOST comforting and liberating!
Morning Glory - the scriptures you gave were exactly the "numbers" Thomas was asking for - just not wanting to "hear" obviously, also very telling that he interprets the scriptures you quoted close to being "insulting." GOD IS SOVEREIGN. That says it ALL!
If understanding the eternal plan of GOD (and can think outside our understanding of time, age-lasting, forever, boxes, which is a WONderful/insightful study itself), understanding WHY GOD created evil will take us into a deeper and scripturally sound understanding on why He created man, His ultimate purpose for him, and how we spend eternity and what that will look like.
"For from Him and through Him and to Him are ALL things. For ALL things originate with Him and come from Him; ALL things live through Him, and ALL things center in and tend to consummate and to end in Him. To Him be glory forever!" ("to EVERYthing there is a season and a purpose..." and "EVERY man in his own time...").
After knowing in our knower that GOD is Sovereign (otherwise, we will always question whether whatever happens is of Him or not), and taking such HUGE emphasis off the possible overriding power of satan (I've been convicted of using a capitol S as many also use a capitol G - not wanting to give him the same "place" of importance as most spell God - it's a personal thing, and yes i know that the Bible spells it that way - anyway) here are a few scriptures i've found to support that GOD created evil (for His ultimate purpose, don't forget);
The word "evil" in Hebrew is "ra" which is used throughout the O.T. to denote wickedness, sin and wrongdoing in over 500 passages. Gen. 6:5 "The Lord saw that the wickedness of man was great in the earth, and that every imagination and intention of all human thinking was only evil continually."
Gen. 3:1 "Now the serpent was more subtle and crafty than any living creature of the field which the Lord GOD had made. He (satan) said to the woman..."
Is. 45:7 "I form the light and create darkness, I make peace and create evil. I am the LORD Who do these things."
Is. 54:16 "Behold, I have created the smith who blows on the fire of coals and who produces a weapon FOR ITS PURPOSE, and I have created the devastator to destroy."
(:17 is great news)
Rev. 12:8-9 "But they were defeated and there was no room found for them in heaven any longer. And the huge dragon was cast down and out, that AGES-old serpent, who is called the devil and satan, he who is the seducer (deceiver) of all humanity the world over; he was forced out and down to the earth and his angels were flung along with him.
Rev. 20:2 "...the angel descending from heaven gripped and overpowered the dragon, that old serpent of primeval times, who is the devil and satan, and bound him for a thousand years...until the thousand years were at an end, after that he must be liberated for a short time."
Rom. 9:22 "What if GOD, although fully intending to show (the awfulness of) His wrath and to make known His power and authority, has tolerated with much patience the vessels of His anger which are ripe for destruction?"
Job 2:10 "...what? shall we accept (only) good at the hand of GOD and shall we not accept (also) misfortune and what is of a bad nature?"
Ex. 4:11 "And the Lord said to him, Who has made man's mouth? Or who makes the dumb, or deaf, or the seeing or the blind? Is it not I, the Lord?"
Prov. 16:4 "The Lord has made everything to its own end and HIS OWN PURPOSE: even the wicked (are fitted for their role, such as Pharoah, Saul. Judas Iscariot...) for the day of calamity and evil..."
Deut. 2:30 "...for the Lord your GOD hardened his spirit, and made his heart obstinate that He might give him into your hand as at this day."
Jn. 9:2-3 "Jesus answered, It was not that this man or his parents sinned; but he was born blind in order that THE WORKINGS OF GOD SHOULD BE MANIFESTED in him.
1 Cor 5:5 "You are to deliver this man over to satan for physical discipline - to destroy carnal lusts - that his spirit may be saved in the day of the Lord Jesus." (just one more part of His overall PLAN).
One of the mysteries of GOD's great purpose being executed throughout the ages (a huge study in itself), is why He chose to work a divine interplay of good and evil, the negative and positive, the emptiness and fulness, the bondage and then the liberation. We may not, at present time, comprehend all the ramifications of why it is essential that He would use, and interplay evil with the good, in our development unto spiritual maturity. But it brings a new rest within just to know that ALL THINGS are out of GOD, and that HE is in perfect control of all the present process, "working ALL things after the counsel of His own will." Eph. 1:11
"For the creation was subjected to frailty - to futility, condemned to frustration - not because of some intentional fault on its part, BUT BY THE WILL OF HIM WHO SO SUBJECTED IT. Yet with the hope that nature (creation) itself will be set free from its bondage to decay and corruption and gain an entrance into the glorious freedom of GOD's children" Rom. 8:20-21
