I think he is definitely a sociopath/liar/scumbag and in spite of the fact that common sense says/shows he did it, I'm afraid that it will be at least a hung jury.
Being a purely circumstantial case, without evidence, it was a steep hill for the prosecution from the beginning. Although 99%+ of defendants should never testify, him admitting that he is a liar/cheat, but could never murder his own child and wife...has helped his case IMHO. While I believe the prosecutor has done a decent job overall, he has also made some missteps of which Murdaugh has taken full advantage.
Let's face it, a normal person could never imagine killing their own family, especially over money/other matters, so it's pretty easy to see at least one juror who will believe he didn't do it.
Add the fact that he will serve time for his admitted law breaking on the other stuff, thereby some type of 'justice' will still be served, I predict that the thought
"if we don't convict him on the murders, he'll still be punished" - will unfortunately allow him to get away with this heinous crime.
