1- it will make me feel better. 

2- i really dont think the ork is that much of a bad ass that his death will simply tear open a new warp storm... 

3- Ok, deamons might happen. Probably would happen. The Eldar would be dealing with that first giving me time to gtfo if i need to. 

4- if he is such a badass that his death will create a new warpstorm wtf are you doing here? go start your own WAAAGH!!! 

5- it will mean the ork is dead... which solves several problems.

oh, and 6- i think your deamons will happen thing is an excuse to keep the ork around by threat of demons. Personally im thinking of how i can get the ork into an airlock and let the deamons happen in the vacuum of space.
