Anakin refusing to wipe R2's memory was a plot point of The Clone Wars animated series, they had to rescue him when he went missing because the info he had in his memory could be dangerous if it fell into the CIS's hands.
IIRC Obi-Wan in the same story arc also didn't understand why Anakin cared for R2 so much.
It's funny how R2 started as Padme's droid, and C-3PO was Anakin's, and they ended up getting swapped around.
