Well all sematics aside, terminology being open to interpetation and all, simply based on the information provided:
FRH i would have to say i think a dominant that pushes his slave to far or ignores his properties needs to the exclusion of acknowleging his girls hard limits (safe words or not) and esculates punishment instead of comunicating amlicably isnt a very wise person and isnt really serving even his own needs but giving in to brutality and isnt any better than a criminal.
To truely have an enjoyable fufiling relationship of any kind, all parties involved must have a dynamic that allows for them to mutually thrive.
A slave should be a dominants most prized possession. Only a fool damages unduely or even destroys his most valuable piece of property.
I know some of you may take exception to my terminology, i do consider myself my owners property in total, (D/s. M/s whatever you wish to call us lol) -we prefer owner and slave or Master and kajira, however you lable us; i trust he is wise enough to do what is right and i would never in a hundred years expect to see him treat me the way the so called dom treated his sub in the original post FRH described...period.
After all what could be better than owning a truely joyful and willing pleasure slave who freely devotes her life to yours?
Who lives by your command becuase instead of brutally crushing her will you instaed did as my owner likes to say so much better than i and :
"coax forth truely willing submission, like the sun a flower's petals with dawns embrace."
