Does that mean Barclay committed mass murder at the end of "Hollow Pursuits" when he deleted all Barclay programs*? Because, you know, the Three Musketeers, pie-munching Wesley, Mini-me Number One, the Goddess of Empathy, all gone bye-bye.
*Except Program 9.
AFAIK, they weren't altered by a glitch that removed their perception filters...which is apparently enough to create Moriarty-lites.
