I consider preservation of human life a terminal goal as opposed to the intermediate goal that is personal freedom.

Uh, wow. That's exactly backwards for me. Otherwise, With Folded Hands would be a utopia rather than the dystopia most agree it is.

Likewise, your stance appears to rate slave rebellions as worse than the slaves obeying quietly -- you have to go to secondary assertions such as "slave societies will undervalue their slaves and waste their lives", which is not entirely self-evident.
