I think the OP's thought is heartfelt and well-intended but misguided. No, this is not what we needed, and there is nothing good about it.
Is it possible that when the dust settles and the deaths have been rung up and the damage done, there will be some good to be found in the changes made or decency shown under stress? Yes, but that will not make the event itself "needed" or "good."
As for the thread's discussion of God being responsible, well, the mystery of evil and suffering has occupied the great minds of our race going back thousands of years.
The traditional Christian view, as figuratively depicted in the Bible's creation story and later expounded by the Apostle Paul and other Church fathers, is that suffering and death entered the world, and have remained there as an existential human condition, because of mankind's original rebellion against God -- a rebellion continually replayed throughout history.
In Christian theology, suffering is never good in itself but can be redemptive, which is the message of the most fundamental Christian symbol of all: the cross.
I realize many here will disagree, and I respect that, though it's unfortunate that some feel the need to do so in defensive and disrespectful terms. If you're secure and confident in your beliefs, you don't need to pour scorn on that of others.
Coming back to the pandemic, we're living through history, the bad kind, for sure. I don't see any good options -- or at least any that don't come with their own huge problems. I think prayer isn't such a bad idea at a time like this.
