This seems odd to me, though I'm not saying you're wrong. From the inside, my values seem far more akin to habits or reflexes than to time-indexed memories.

I imagine Obliviated!me still having a NO DON'T reaction when asked to support a purpose opposed to my previous goals, because verbalised goals flow from wordless moral habits; not the other way around. (assuming a possibly inconsistent scenario where I retain enough language for someone to expect to manipulate me)
