They casting soul trap on your self is a fate worse then death the soul gem could be and and used then your soul will be trapped forever in the Soul Cairn were it would wander aimlesly without rest or peace and becoming your own thrall won't work either becuse you would be in an endless loop of death and rebirth until the spell either wore off or was stopped by some in which case you would die.
