Personally, I think the Anakin confessing to murder scene, while incredibly poorly executed, has a purpose. A key part of Padme and Anakin’s relationship dynamic is that it’s dysfunctional. She’s an enabler of his behavior. While I think the literal admittance to killing kids and Padme’s acceptance is ridiculous, I think too many fan edits, including L8wrtr’s and Hal’s, go too far to remove the dysfunctional aspects of the relationship. To see how this can be written well and how it adds to the characters, check out the Rush Clovis Arc in Season 6 of the Clone Wars.
