On a more serious note:

I think.... this is all Emma's twisted way, of having her loved ones redeem themselves. By stealing their memories, she is essentially putting them in the same situation they were in, when they all arrived in Camelot. Emma wants to see if history will repeat itself, or if her friends and family learned their lesson.
