The most messed up thing I wanted to do was on the mission Those! where I had to go & check on that kids father. Once I discovered he was dead I wanted to pick up his body & carry it to the kid to show him, holding him up standing & facing door of the shelter the kid waits in, as I opened the door...Surprise! I found your Dad!
Unfortunately the game wouldn't let me carry his dead dad out of the house, so I had to settle for stuffing a few heads & limbs of some raiders & blew up with a grenade into the shelter with the kid, you know, to keep him company & give him something to play with in the pitch black shelter while I went off to kill the ants. Also the make sure he was super safe I put a mine outside the door, so nobody could sneak up on him...
But I got distracted doing that mission by some Brotherhood of Steel guys & Super Mutants, so I haven't completed it yet or gone back to the shelter, the kid's still in there... in the dark... with his 'toys'.
