Yeah but it’s less like the reaction to mass murder and more like a case of indigestion.
Could say the same or worse about Leia to her home planet. It’s not Rabbit Hole.
To be fair, we never saw her reaction to its actual destruction, only getting back to her hours later.
Nevertheless, this is a failure of SW '77.
Or just a deliberate creative decision. Leia is still technically a supporting character to Luke, so it makes sense to merely imply some character moments. After all, they shot a reaction for her planet’s destruction but chose to cut it, probably to keep the focus on Luke.
