It's not him deciding, it's you deciding what happens to him.  He wouldn't want to be killed or captured, he'd just be written out of the game that way.<br/><br/>Taking the 'be captured and escape' option would let him still be alive and free at the end of the day, and also make it easier for Ulth to get his character more involved in the game.  I'm pretty sure that's Ulth offering you a compromise...
