One of the pros of adding back in the scene with Anakin and Padmé after he kills the Tusken raiders is where he sets up the whole “I will learn to stop people from dying” thing, but this is a lot less necessary if you’re mostly cutting that out of ROTS.
In my edit I found a way to cut out him talking about his slaughter, and I think it works pretty well. But saving Padmé is a big part of my ROTS.
