Mankind has spent incalculable time in the defense of God who permits (with varying degrees of specificity) the existence of evil. Paul Young tackles the issue in a very successful book "The Shack".
He does so in the context of the serial murder of innocent young girls. (What is the most wretched and vile crime you can think of?) He could have done so in a larger context - hunger, thirst, homelessness, sickness, slavery, abuse - but he confines the story to the evil man does. Man is more ingenious than the mosquito and thus more capable of dramatic malevolence. When is the last time a book about mosquitoes made the New York Times best seller list? Mosquitos kill a hundred times more people than AIDS.
The mechanism is a real tragedy about "Mack", the murder of Mack's daughter while on a camping trip, an invitation from God in Mack's mailbox, and 48 hours with the Trinity - a female African American "Papa", a male Jewish "Jesus", and a female Asian "Spirit".
The method is awareness of one's self and forgiveness (especially of God but even of the killer who eventually meets Justice) in a fairly orthodox framework. What is not there is the institutional Church and the wrath of a vengeful God. This is all about a personal relationship with God - the ground of all being (Panentheism).
My own view is that a world in which we are possible is also a world that harbors mosquitoes. If it were "perfect" there would be no room for us. I'll take a bite out of the Apple of Life.
People usually either love or hate this book. Strangely, I am in the middle. I believe we evolve spiritually at the expense of dogma and doctrine and progress with the practice of love, kindness, patience (Good grief - I sound like another Paul).
