In a wider effort to reorient Anakin’s turn to Vader to being more about power then attachment (something I’m trying to accomplish with my “Vader Edition” prequel trilogy), what if part of the reason the Council rejects Anakin is because he secretly craves revenge on his master? I’d be 100% understandable, he was a slave. I don’t think there was ever a slave that didn’t want to give their master what they deserved.
The part of him missing his mother would still be incorporated, but I think it’d go a long way to show that Anakin had power-hungry tendencies from the beginning which ties into his past as a slave.
