I think this progression will do no more than force an existing moral question into the open. What is the moral quality of a thought?

Personally I believe that even unspoken thoughts can have a strong moral dimension for the individual, though of course I see no legal dimension.

One aspect of this will be does our indulgence of our own negative fantasies weaken our capability to act rightly when presented with a real world moral choice and does that make us culpable...or more culpable if we make a wrong choice.
