IMO, the most important aspect of the sexting is how it will play for the jury if this case goes to trial. I'm sure people do it (I don't) and it certainly doesn't mean those who do end up murdering their children. OTOH, most people, whether they do it or not, or even wish they could do it are reluctant to defend it, especially when sitting on a jury with a group of their peers.
Remember the children's pastor who testified at the probable cause hearing and how she back-pedaled and tried to distance herself from RH when she learned about RH's sexting? That's the reaction we want jury members to have if we want this piece of cow pie convicted.
The sexting itself is irrelevant; what's relevant is how it connects to underage minors and to showing the callousness of a depraved father masturbating while his child dies. The bonus is that no juror wants to present themselves as lacking in morals.
