On the one hand, he's the :spotted owl: who got me in this mess in the first place. I am motivated solely by revenge - I want to blast Benny's head 20 feet from his body. But where does House fall on the scale?
On the other hand, House was responsible for Victor pulling me back from the dead.
I don't know if killing House and taking over New Vegas would make me just as bad as the rest of the mongrels scrapping over the desert. After all, House isn't out for absolute power in the way Benny, the NCR or Legion are. He uses people as pawns, but in New Vegas that's really a lesser crime.
What did you do at this point? Kill him and take over? Let him live? How did you justify your actions?
