Just thinking about loud.
Just to me it's not a case of Sisko being the absolute victim, even though it was normal for him (who would say otherwise) to assign blame to Picard in some sense.
There's not clear indication that Sisko blames Picard for Wolf 359. The animosity is symbolic of Sisko's own psychology, his inability to move beyond his wife's death. To that extent, Sisko is a reminder of the tragedy that Sisko has faced. It's a bit much to claim that Sisko is "the absolute victim," as if he is just acting selfishly, even when in daily life people might normally have difficulty facing people indirectly involved in their loved ones' deaths.
