Actually, I would have loved that, because personally, I think that it would have been more in-character for Worf to complete the mission, and set all personal feelings aside. Wouldn't his Klingon honourrrrrrrrrr command that? I might be wrong, but it's what I think he should have done.... if I had written this as a fanfic, that's what he would
have done. Difficult decision, something he would have to live with for the rest of his life.
Instead, we got a diabolus ex machina with teh evulz Dukat to blame. Way to throw awesome character development out the airlock.
