I'd be carefull of console kill commands. I console killed a prosttute to get her outfit in one part of the strip everything was ok zoned into the other area and the robots opened fire. It was definitely related to console killing the npc. Also I console killed Lucius in Caesars tent and everyone went hostile.
^This.
Using the 'kill' console command is
not 'silent' and will alert anyone in the vicinity, and unless you have a ridiculous amount of rep with that faction they will attack immediately.
As such, it should generally be reserved for cases where a target glitches and does not die at zero health. True, the vast majority of these have been patched out, but a few are still lurking out there. It can be used on critters with no problems, although doing so with someone's pet dog is going to get you shot at. It should absolutely
not be used on quest NPCs, for obvious reasons.
