I was going to put this up a while ago. But I accidentally deleted the entire post after I had finnished...I do that a lot. Anyways, a few weeks ago, I was thinking about Animorphs (obviously) and I started to think about the Voluntary Controllers. From what we've seen in the series, the Voluntary hosts are looked down upon, like the scum of the earth. We heard that most Voluntaries give up their freedom because they can't handle their own lives, or because they're just really ambitious. I remember reading about how disgusted the kids were when they saw what happened to the Voluntary Controllers during the feeding process--the special room with the Full House Reruns (which makes me think that they can't have it all good, since that particular show isn't exactly "good"...but, I digress). Over all, the opinion of the Animorphs concerning the Voluntaries is generally low.
But I think we can at least sympathize with these unfortunate people. Couldn't we at least try to understand? Chapman, for instance, gave up his own freedom to save his daughter. Whatever Chapman was like as a child (Andalite chronicles) you can't deny that he was thinking of his daughter's well being. Taylor turned to the Yeerks to get her beauty back. Sure, it's a superficial reason, but I can understand why she'd give up her free will. Obviously, Taylor only had her looks. Once that went away, everyone she thought loved or cared about her went with it.
And if you don't agree with my two examples, let me try to paint you a different scenario. A middle aged father of two or three recently lost his job. His wife's income isn't enough to support the family. The market isn't stable, and he can't find another job. The father starts to get stressed: his life has taken a turn, he has his children's future to think of, and he starts to slink away into depression.
Scenario father then hears about the Sharing--through a friend or priest or what have you--and decides to check out this Yeerk Front. After a few weeks of attending the meetings, he is offered a chance to be a "full memeber". The father, realizing that the Sharing is really a front organization, thinks about his family. The Yeerks offer him stability (probably a lie). What do you think this guy's going to do?
And then there are the loners, homeless and depressed. People who, like I already said, dislike their lives. I guess you can understand why they'd choose to have someone else take the reins, so to speak. Escapism.
I can understand Voluntary Controllers. But I don't understand Andalite traitors.
