more torturing

The memory of her each hour had grown clearer, more torturing.

And what made this the more torturing to him was the fact that he always saw her with an accusing look on her face.

And as he died I imagine there was no more torturing thought than that he had left his work unfinished.

No "spiritual exercise" devised by the discipline of piety could have been more torturing; but its very cruelty attracted her.

It was even more torturing than before, as was also the wild pain in my head, if such a thing could be.
