The Eddington arc was great. Especially For the Uniform
, which is one of my all-time favorite episodes of DS9.
Eddington was a villain...but he was a sympathetic one in the sense that...well, you'd be mad too if you were arbitrarily kicked out of your homes and told to move somewhere else...quite possibly away from family, friends and farms/business that had taken years to establish.
What he did was wrong, of course...but while the means were a serious problem, the ends he was shooting for where really not all that unreasonable.
So it wasn't a black & white issue of right and wrong. It was in the gray zone.
