Yes, I agree. The prosecutors opted to go to trial with the ambiguous dna evidence on the clothing--the rationale being better to catch one chicken than wait for the possibility of catching two or more in the bush--risking the case going cold. My thought in the beginning was that Steven C's intent was to cause a miscarriage of his baby, not kill Charlie. That would explain his horror response in court when viewing what was found of her remains--the split jaw and fingernail pieces, etc. Who else might have been involved, as well as the circumstances of Charlie's death, at this point, is so convoluted with mismatched evidence, I think it is nearly impossible to prove factually in this trial what actually happened to Charlie. If the Judge gives instructions to the jury allowing for a lesser charge, a voluntary manslaughter conviction might be the end result.
Eventually, one of them missed the input, the world shook, and the flight the Losties were on came down on a beach and the new settlers arrived, where they gradually met the old inhabitants who were mostly Hostiles. Everyone on the flight had previously done something pretty bad in life, and they got a second chance.
