Fallout 3 Megaton/Tenpenny tower problem

[finty]

At the start of my Fallout 3 game I decided to rig the nuke in megaton to explode but never visited tenpenny tower to push the button. As I played through I decided to go the good karma route. I'm a right bit on now. I want to disarm the bomb to get a house in megaton and good karma but I'm not given the option to do this. Is it because I have already rigged the bomb? Is there any way to now disarm the bomb?

If I had to guess I'd say at this point you can either leave the bomb or set it off.

Yeah looks that way. Don't really want to set it off so I guess I won't be finishing this quest.

I recommend setting it off. It's awesome! plus megaton starts getting annoying after a while and the house there is a piece of shit.

set it off. You can become good even after going completely evil. I had a hard time finishing evil because the final few quests really make it hard to do anything but good or neutral. Nuke those slimey bastards, kill everyone they all deserve it.

Sorry, I hadn't been the "Fallout" me in a while.

I am loving this game.

Burke practically orgasms when you set it off.
