Well it does make sense if you think about it. Ekrom owns a ship and a Merc crew, even something happened to get him banned from the citadel he'd be fine. The other however don't have the luxury of their own space faring vehicle and thus need to at least keep a somewhat good standing there. 
(Plus it couldn't hurt to have internal conflicts about when we do and don't kill people ;) )
