Is it possible to play through as a House character without having to make your character a terrorist?

I don't like the BOS, but I can't rationalize an excuse for my character to sneak in and massacre a group of individuals who aren't even hostile. Killing BOS members in a gun fight is one thing, but House is asking for the unthinkable.

I think House might be Vegas's best shot to return to pre-war glory, but the price is currently too steep.

Is there any way to complete the House campaign without killing all the BOS in cold blood? It just seems that unless your character is a total psychopath, then there is no way that they could be convinced to carry out mass killings in cold blood.

Can House win without becoming the Bin Laden of the Mojave?

Just activate the self-destruct. A loud alarm goes off to alert them that they need to evacuate. Not your fault if they decide to stick around.

Well in pretty much every ending besides the one where the BoS sides with the NCR, the Brotherhood raids caravans for high tech.

Sounds like terrorism, doesn't it? The Brotherhood won't accept House having so much tech, so he needs to wipe them out.

And no, you have to kill them to side with House.
