Yeah, this is what I was thinking. I was trying to envision an interaction between Lois and Clark where she expresses sympathy at having turned his life upside down while maintaining that she doesn't feel guilty or that she "did what she had to," but I couldn't picture a scene like that where Lois came across as anything other than an insensitive prick. I mean just picture her showing up at his door and saying something like "I'm sorry that your life was turned upside down Clark, but I did what I had to do and I won't apologize for that." Who the hell would accept an apology like that from someone they're already upset with? There are times where someone is so negatively impacted that it doesn't matter whether or not you had a good reason, you still bloody apologize.
