Actually not at all, since the understanding that has been given to me makes a congruent picture of "God is Good" which is in the Bible quite a few times unlike this one verse which you want to view as corrupting the notion that God is Good. As I, and many, many others now and long before me (and way smarter than me) have maintained, you cannot say God creates evil and mean that in a moral sense without corrupting the idea that God is All Good.
It may be hard for some Protestants to imagine, but people did not wake up 500 years ago and start questioning everything the Church teaches. People actually read and questioned the various teachings throughout the last 2 millennium and we have records of the more testy debates, including ones that reached high level in the Church clergy and were supported by a majority of them including Popes, which in at least one case the Spirit led a few men supporting one Bishop against a major heresy. So it is not like we have "discovered" anything new about moral truths in the last 500 years. And certainly not like someone was reading Isaiah 45 one day and suddenly [bless and do not curse][bless and do not curse][bless and do not curse], God does do evil. People have also looked at a lot of OT verses and in an attempt to justify how THEY THINK those verses are to be literally understood along side the idea that God is Good to arrive a whole host of claims about God - including that heresy the OT God is a different God or the heresy that God changes. Just because someone reads and claims the Bible literally says something, does not mean it is true that what is meant to express matches that claim.
So I too could say WOW, you want to dispute that God is Good by claiming He does evil. Misery and distress are indeed evils, and we call clamaties "evil" because they cause misery and distress. There is no such thing as a good tornado or bad tornado. Such things are a part of the natural order of things, the way He made this world to run. A tornado results from natural atmospheric conditions required in the production and transportation of water which supports all life on earth. A tornado can and does kill people and destroy things, which is bad and why we can and people call tornadoes evil. Even heard one person describe one as "pure evil" when he looked at it. But those descriptions are expressing how a tornado makes us feel when the bad effects of us threaten us directly, and those effects can be devastating. It still does not mean a tornado is actually "evil" in a moral sense. All such things are morally neutral, but because they can cause misery and distress we tend describe them as "evil".
None the less, God certainly ALLOWS (not creates) such "evil" to exist for His own Good and Glory, which we cannot possibly see. We know He allows it because it happens and He could stop such things and perhaps does stop some of them or even directs their course of misery and destruction for His Own Purpose. He has also used them demonstratively, most notable and memorable, with what He had Moses call down on the Egyptians. We can certainly consider those events as being directed by God, but it does not mean God does evil. The tornado some see as standing before the Egyptian army all day is not evil either, it is morally neutral. If that was indeed a tornado, God is certainly shown directing it's course and He is certainly capable of doing that. But we do not have to imagine that tornado as indicating God does the opposite of what He is. It makes no logical sense to suggest the All Good creates something opposed to Good. In fact to say other wise means we must imagine God having a Will that shifts from a singular focus on All Good to looking away from that. We should not be able to support such a notion, reject it entirely as clearly God is All Good.
So if someone asks me does Isaiah 45 say God creates evil, my only answer can be yes it literally says as much, BUT it cannot be understood in any way that is opposed to the many Scriptures saying God is Good. I do not see how you can have that verse your way and not be forced to admit that God is NOT All Good if you maintain He can create that which is opposed to Himself, which the Scriptures deny repeatedly in declaring "He is Good" and actually He Alone is Good.
