Our typical west coast BoS supporters exhibit clear signs of sadism, enjoying the prospect of torturing a man who placed trust in them and further betraying a separate group of people for 'kicks'. They also tend to be obsessed with anything big and shiny and some leading psychologists think this stems from the need to compensate.
"Compensate"? Projecting a bit, are we?
Seriously though, that is a little sick. You want to torture someone for laughs? Nice.
When this situation came up in my first playthrough......the moment I realized he wouldn't be reasonable about it I went to the basemant and emptied a Laser RCW into him. My only regret was that they didn't provide me the dialog option to explain to him he was sadly mistaken if he thought my loyalty was for sale. He thought he could buy people if he pushed enough caps at them....he was wrong about Benny, and just as wrong about me though for opposite reasons.
Hamnade man nails the problem from House's view. He dislikes the NCR (for good reason, since they want to kill him and take his home) and if you reconcile the Kings and NCR he sees it as them supporting the NCR. Of his decisions this is the one I most disagree with (though, since I found out about it, it doesn't come to pass).
The NCR tried to talk to him....he could have gotten a good deal if he wanted, but his real plan was to let the NCR bleed itself white protecting the Dam (and by default him) and stall for time until he could get the chip back and then say to the NCR, "the Moor has done his duty, the Moor can go". If the NCR was willing to take the hand of one of thier bitterest enemies...the BoS...to hold onto the Dam, House could have wrote his own deal easily. And the Kings....House created them by casting those he had no use for into Freeside to fend for themselves. It wouldn't have taken much to stabilize Freeside and secure the King's loyalty...and freezing the NCR out from the getgo...but he flat out didn't care what happens in Freeside. But if they take NCR assistance, he punishes them for "disloyalty" to him. Talk about callous.
