Jack, bereaved survivors of the decedent, if they're motivated by revenge and spite, won't be deterred by a low net worth on the potential defendant's side. If their goal is to ruin you, they achieve that by bankrupting you with legal defense fees as thoroughly as they would by winning a judgment against you. They may also choose to frame your shooting of the burglar, for example, as negligent, so they can go after your homeowner liability insurance.
I don't keep track of defendants' net worth. None of my business.
