Characterization
While sharing the same core values of Captains Jean-Luc Picard and Kathryn Janeway, Sisko shows a tendency to compromise those values in extreme situations. The most striking example is in the episode "In the Pale Moonlight", in which Sisko lies, obstructs justice, and is an unwitting accomplice in murder in order to turn the tide in the Dominion War. Afterward, Sisko records a personal log regarding his feelings about the entire affair, lamenting the fact that he appears to feel no remorse for his actions (which, by bringing the Romulans into the war, significantly increase the Federation's chances of survival) before having the computer delete the entire log entry.
Another example of this Machiavellian approach can be found in the episode "For the Uniform", in which Sisko poisons the atmosphere of a Maquis colony in order to catch the traitorous Michael Eddington.
Sisko demonstrates a bold and no nonsense persona to the point of exasperation, even to the extent of his best friend (the latter host of the Dax symbiont shown in the series, Ezri) stating that his personality intimidates Worf. Relative to other Star Trek captains, Sisko shows strength in strategic/operational military planning, as evidenced by his chief role in the Federation's Dominion War effort. While not as schooled in philosophy as Jean-Luc Picard, or scientifically geared as Kathryn Janeway, Sisko also highlights strength in engineering capacities (as seen in "Explorers", "The Visitor" and "Civil Defense") having served before being posted on Deep Space Nine as the commander of the Federation Shipyards at Utopia Planitia on Mars.
