I think that Ansem is absolutely responsible for all the trouble happening in Kingdom Hearts series. His research just set the ripples of the storyline. Who knows, the whole thing could start off the story differently if someone else were to continue his research, just like what NobodiesShadowX said. The events continue on with every choice made. Even though he tried to stop it, that has set more events in the story, ones that can be good or bad.[COLOR]
