I am a slave and do not have a safe word.but, before i submitted to lady she offered me the option of having one.she was thrilled that i didn't want one, but she let me make the choice. in my opinion the fact that she would cut all ties with him if he uses his safe word is very alarming to me.It says to me that she does not care about him at all, or for his safety.I would tell him to think really hard about submitting himself to some one like that.there are a lot of sadists out there that get off on doing real harm to people.
