If Clark had to make love to her himself to stop her from willingly marrying Luthor to save the Daily Planet, it was a sacrifice he was prepared to make.
Some things were worse than death.
Clark would kill her with sex to prevent her from marrying Luthor? That's .... not right. Why would Clark contemplate murdering her? Wouldn't he just run away with her like he was thinking before?
I like how you addressed the insurance issue. It never made sense to me why he would insure the business with his own insurance company. That's just moving money from one pocket to another, and he would still have the loss of the building. It doesn't net him anything.
