To be honest, I thought Three Dog talking about the Ghouls killing everyone in the tower was a game bug - one of those things where parts of the game get the possible outcomes confused.

When I came back, and saw that it really happened, I really did feel pretty betrayed. I double-checked to make sure "Daring" Dashwood, honorary Ghoul that he was, was among the murdered. It felt very important to verify that. Once I found out that yes, he was, I went to the top of Tenpenny tower, and put a magnum slug through Roy's skull.

The game wasn't very pleased with my choice, and tried to tell me I did a bad, negative-Karma sort of thing. No, game. I refuse to accept that. Sure, I'd have preferred to drag that bastard somewhere for a trial - maybe to Undercity, so he couldn't claim it was "Anti-Ghoul bigotry", but since the game didn't give me that option, I had to do what I could.

The rest of the Ghouls can live there - but Roy had to be put down.
