I mean, DS9 was almost as much in the boonies as Voyager. Assistance was limited, and there were limitations on what he could do, as he was only running the station at the behest of the Bajoran government, not as a true representative of the Federation.
It also introduced facets of war, even before it became a full blown thing in the later seasons. He wasn't always on the side of the angels... because there are no angels in war. War only ever makes demons.
It doesn't excuse his actions, but it doesn't make them truly inexcusable either. They both operated in much more of a grey area than either of the two previous series.
