Is this a bad thing?

I'm not interested in "evil" quests for bad characters. I thought these guys were the equivalent of Raiders from the last game, so I wiped out the prison, except for Meyers, who is now the sheriff at Primm.

I hope the game isn't contrived enough that I must load up an older save and do things differently. I'm hoping all I missed out on was a little reputation boost with the NCR.
