dogmatic is the ONLY way. on janos you kill all xenos, purge governor and her cultists AND execute rebels. mercy is not an option. feels good to be good.
You can be dogmatic and not be kill them all type I spared the young rebel cause unlike those decadent s... worshiping wardens he had cojones and took part in loyalist uprising against heretics and wounded some of them, there is option there to put him under arrest until later, the empire needs the people like him.
Also spared the rebels and those prisoners who fought against Drukhari on prison planet and those who followed the ''commissar'', My Commissar-Trader was more like Cain or Gaunt, I killed only heretics, traitors and cowards but not brave men who might be... led astray, after all they were just commoners and should be led better.
Totally shot this arab mystery meat slooot though when she admitted to be IG deserter, should do it earlier but unfortunately her contacts did gave me mucho Profit points, some xeno-trade is allowed for Rouge Trader to do, heck you are allowed to ''ally'' with Eldars to fight Heretics as long as you remember to... take care of them later which my CT did.
Game needed more morality points in game cause some Iconoclast options were simply much better like selling the food to the Liedge or destroying rather than turning off false beacon, I took all dogmatic ones I could and still was behind the curve.
Sometimes you also do dogmatic choices and are not giving points this game really needs one year more in beta testing before the release, its heresy to sell it in such state but what you expect from heretics who escaped Holy Imperium of Man to Cyprus.
