I do not understand why Worf got a mark on his record. Sisko or whoever should have known better then to pair up a husband and wife on a mission that dangerous. Who would not have made the same decision Worf made.
Seems a valid point to me, but this is the same Federation that sent ships into battle against the Borg with civilians and families on board. Even the Ferengi ridiculed this behavior in TNG's Rascals when Riker tried defending it. The mindset is there that either Starfleet officers are expected to function regardless of their family's proximity, or they're just turning a blind eye to what seems obvious to us "primitive" humans that they can be a liability in a dangerous setting.
