I think of this every time somebody mentions Eddington. Remember "Our Man Bashir"? In that episode, he worked as hard as anyone else on the station to get Sisko and crew out of the station computer in which they were trapped (and their bodies out of the holodeck simulation). Given what we would later learn of Eddington, wouldn't he have just let them die?
Um, why? What would there be to gain? Sure, he'd probably end up in command of the station for a bit, but the inconvenience of a massive Starfleet investigation would probably hinder any Maquis plans he had in mind.
Not just because he was Maquis - and therefore would consider Sisko and crew the enemy, just on the face of it -
Like he kept saying - "Our quarrel is with the Cardassians, not the Federation." If his attitude really was that Sisko and co were 'the enemy' then on a Starfleet-run Bajoran space station about 60% of the people he met would have been 'the enemy'. He'd have been a paranoid nutcase in no time...
but Eddington himself was extra nasty in that regard.
But was he though? Remember, it's not just in Our Man Bashir he had chances to kill the rest of the senior staff and chose not to. He had the perfect chance to kill Dax in Rejoined, Kira in For the Cause, or the entire Defiant crew in For the Uniform. But he didn't.
