Aside from the fact that you can't phrase it without mentioning game mechanics (if you say something like "do not attempt to resist as I oppress your will", that leaves no definited value of what counts as resisting; a Will save might not count as intentional defiance, and there are other things like spell resistance that the target might not know they don't possess, and might thus refrain from trying unsuccessfully to use), it's pretty much the same as ordering the creature to kill itself. A magical compulsion is used to impress a creature into service, not oblivion. If the spell is capable of causing the target's death, it should generally be written so explicitly.
