No, I know what you mean. Except that Jade did this SO that she and others could live in peace. She had motivation in the form of one person (Oliver. The now Sandslash Morph) and that's all it took. If she died and he lived, but the world became a better place, that would be just fine with her. She jumped into the whole thing. She never really thought about how Morphing would effect her later.
None of them can really go back to living like they did before. But then, things will never be the same so even if they hadn't morphed....it would still be weird, you know? If Jade had stayed home and took it all, instead of fighting, the world would still be effed up.
