I’m inclined to agree with @Superdude - he might not have been a great partner but there are far more indicators that it was an accident (she hardly had any food, she was using a phone rather than map to navigate, she didn’t have a personal locator beacon, didn’t have a clear idea of the route she was taking, was in the Pyrenees at a very dodgy time of year where it would be sub zero temps at night with no winter tent). I think unless you’ve spent a lot of time in the mountains it’s perhaps difficult to grasp just how dangerous it can be, and how quickly you can get into trouble if you’re alone.I think you have a very kind mind. And what you state is definitely plausible.
I like some others, view his past & present behaviour as seamless.
He is predictable because of his inner rage. IMO.
