In the Pale Moonlight

Personally, I find it a bit hard to understand what Sisko does that is so terrible in this episode. Okay he bribes Quark, but he has bent the law numerous times before for the Ferengi. He is an accessory to several killings, but he doesn't even know about them until after they happen! And he does get clearence from Starfleet for the operation - we've seen before that Starfleet is willing to authorise lethal force against others on intelligence missions. Picard and co. killed several Cardassians in "Chain of Command" during an invasion of Cardassian territory, for instance. Okay Sisko's actions may be a little less than spotless, but they hardly seem like the great moral burden around his neck that he makes out they are.
