[H.P. Lovecraft/Anything] What fictional characters outside of Lovecraft’s works could survive using the Necronomicon?

I feel like even using it drives people insane due to its contents. Is there anyone in any fictional universe that would be able to use it to their advantage without going mad? And how dangerous would using it make them?

Magic is much more approachable in other worlds. 

In Marvel and the MCU, for example, there is the Darkhold, which is a Necronomicon-style grimoire, and both Dr. Strange and Wanda Maximoff have used without going (completely) nuts.

On the DC side, John Constantine probably considers the Necronomicon light bathroom reading.
