I'd had Fallout 3 spoiled to hell and back on me, so I knew what was coming if I did things Mr. Burke's way. I was all set going into the game to nuke an entire city---I'd seen it on YouTube and thought it was cool.
Until I talked to the people. Gob and Nova, Lucy West, Lucas Simms, the Stahl family, and yes, even Moira Brown, whose infectious cheerfulness resonated with me---in the real world, infectiously cheerful is a quality I look for in people.
I couldn't do it. When I went in and saw Mr. Burke, I popped into VATS and got myself a shiny new toy with a silencer off his corpse. Megaton is MY town in Fallout 3. Clean water for Micky, research for Moira, a happy ending for the Wests...and one defused bomb.
