Right, but again, exalted. This is a feat were it takes all of 30 seconds of DM narration to get rid of it for that player character forever. "Woops, that lady you stopped form getting mugged who just left? She's a drug runner and she's evil. You just helped evil. You loose your exalted feats! Tough break."

I have seen this and similar happen many, many times. If were to consider the feat outside of isolation, all well and good, but that really should be taken into account as well.
