Question about the Michelle Carter texting/suicide case, for any defense lawyer who's here today [View all]

I understand that there are limits to what she can express remorse about while her appeal is still underway, but would her lawyer have told her she couldn't at least say she was sorry just for sending the things? Would even that be taken as an admission of guilt?

I ask this to try an understand why she has shown self-pity at the trial, but not said anything even along the lines of "I didn't cause his death, but I do apologize for sending the texts" compromise her defense?
