An example of free will:
Saintess decided to steal a Nekomimi from the cloning labs. Already outfitted with cutesy clothing and the imoutou persona. However when he decides to the store for milk...
I decide to break in and steal said nekomimi, thus robbing him.
it's free will! I'll instill my values into the nekomimi, and give her back to Saintess when she is respectable and not just a moeblob.
What I mean is people can choose to hurt others while trying to help others, that is choice. I think people choose what they do because of how they were raised, what environment they grew in, etc etc.
O the matter of free will I think it's up to a person tod ecide whether or not they have it. Like going into a relationship, into the cubics or so forth.
Because both ask for you to sacrifice your free will, to some varying degrees. What you want to do, and what you need to do. That is about it.
Oh well, I'll leave it to the less sarcastic, more professional explainers. :]
