I was re-reading part 143 (where they learn about Monique Kahn's death). I think Clark really has no one to blame for his current problems than himself. He is the one who did not trust Lois with information so many times.
I also realized with Lois knowing that Lex is the voyeur, if she, Henderson and Clark pooled what they know they could probably make a circumstantial case against Lex for the murder of Kahn, but I am not sure that would really hold up in court.
