We could speculate many scenarios that could have led to less tragedy. One, I believe, could have been if the father continued to refrain. I realize that my encouragement of intimacy short of PIV activity could have resulted in the same result, with current laws as they are. Given the tragic ending, I find it hard to say he did the right thing.
My post was a proposal for a more sane attitude toward incest. I suggest that including full intercourse in that proposal makes it a much more difficult pill to swallow, especially given the genetic risks in the case of pregnancy.
