Tyranny or Slavery?

If to become a slave is to renounce liberty, then does that not include renouncing the duties and morality of humanity? Not due to dissension but because conforming is no longer necessary.

The implication of slavery is that the individual who claims title is responsible for the well-being and care of that slave, as well as their actions and words. The slave merely follows instruction in return for being kept.

Am I too traditional? Too historical? I don't see much of that description in contemporary pseudo-sexual M/s behaviors.
