I disagree with you, Phoenix. You're working under the assumption that the doctor had reformed enough in that short amount of time prior to regaining the memories from the fifth crystal. Who knows how many years of memories were stored in that? It's not even known how much baggage came with that fifth crystal. It's likely that whatever events happened after his wife died had enough of an impact to make him a sociopath, and override what happened in the short span of time that was this episode.   See 7 other replies

Conscience is based on empathy--the understanding of what it really means to "do unto others as would be done to yourself." Experiencing pain in any form is essential to developing empathy. One can extrapolate from one kind of pain to another. Even if you have never been burned, if someone tells you that burning hurts as bad as getting cut with a knife, you can make the leap of understanding to know that setting fire to someone else would hurt that person, with the understanding of how that might feel, and your conscience would tell you it is wrong to set fire to someone else. Tom did not lose his "new" memories as he regained his old ones. Thus, as he had actually experienced the pain of having his memories stolen, he began to develop remorse, and the wish to know he had "not been a monster." With the final vial of memory restored, he would know that he HAD been "a monster"--but with his new understanding, he should have then had great empathy, remorse and the development of "conscience" to prevent him from doing it again. Even if coerced by his new masters, he would have retained the memory of how it felt, and so would have been wracked with guilt, and with a great reluctance to inflict such pain on the woman he now trusted and cared for. If someone wants to argue the speculation that his new masters erased his new memories, it won't wash: he remembered that Hope had bad memories that she "should not miss." The structural error in this story is the lack of consistency in the ending. You can't have it both ways: either he would have forgotten everything that happened after his memory was "deleted" or he would have remembered it. Having remembered it, he could NOT be the "same person" he was before the erasure and restoration of his old memories. Character is formed cumulatively. Tom WAS reforming--and remembering the past should have strengthened his reformation, not undone it. The writing is flawed. The end narration is idiotic.   See 7 other replies

Fifth crystal.
He was going to use it to prove that he wasn't a monster, she replied, "No, no, no. You don't have to prove anything, I care for you. The man you are now, not the man you were."
Sounds like she was putting her own feelings into the mix to me. They didn't know what the return of his memories would do, he thought he could control himself, her thoughts were founded on her selfish desire to keep him as she liked him. That her concerns came true does not justify her gambling with another person's mind.   See 7 other replies

Sleeping with a memory-loss person is an interesting issue. However at the end, the reason she asked him not to use the fourth crystal was for his benefit not her own. He knew that he probably would turn into a bad person -- he had made bad choices. But this was a choice to not make those same choices. That's the angle the show's going with at least. Interesting choice on his part.   See 7 other replies

It doesn't matter if he made the first move, she still choose to sleep with him. Missing 60% of his memory might as well be considered him not being in his right mind, especially when they both knew he would be regaining it over time.   See 7 other replies
