Marco say "I told you already, I will come with you no matter what. If you want to kill Tsina than do it. These are your life and I know better than to stand between the butcher and the pig. I am not here to understand or to judge you, I will walk your way.
Let’s talk about this family of yours, about this Bratva. The leader, tossed his spouse/girlfriend aside like an old toy once he found a more exotic woman, you. He was so bad at leading that his little Bratva had a coup against him. Led by the same woman that he tossed away like yesterday's news. Vory is organization, and family is metaphors, the social relations of your family were all fractured and dysfunctional long before Tsina led her coup and they were like that due to bad leadership.
Vory is an ORGANIZATION, not a family and thous that seen it as a family were tossed away like yesterday's news. They were blind to intrigue, to discontent and to the obvious fact that violent criminals are dangerous bed partners. You go in, get your revenge but do not lie to yourself again, it is all about money and power. It always have been. Family, honor - they are just methods to keep the members inline, to keep them loyal to the cause.
I am also sure of one other thing, Nikolai did not just 'find' Tsina after so many years. If he really spent all these years searching for her his own Bratva would have tossed him aside long ago. Nobody has this kind of patience. If Tsina manage to stay hidden for 28 years she did not just ‘pop out’. More likely is that she was in the way... in the way of big money and power. If Nikolai could he’d do it himself, but he cannot she is too smart or too powerful for him or he grew more careful over the years. So Nikolai find you and tell you the 'willing butcher’ about your mortal enemy and family and honor and it still works after all these years.
There is no honor in murder but there is honor in mercy. No honor in going out of your way to get money, but honor in charity and in helping people in need. Your way has justice in it Tsina deserves her fate because she wronged you. As for Vory? her only crime was to break what was already a broken and dysfunctional Vory Bratva. Tsina was the leader of the coup, but a coup cannot happen on its own, it requires many discontent people to begin with. That leader just bad at leading, so bad that he got himself removed from office and his followers all killed. Illusions and Lack of realism make you weak. Maybe he believed Vory to be family, perhaps this is why he he did not see it coming, perhaps this is why he is dead and Tsina is alive.
We go to Poland and I will help you with everything you need to finish your business. Do know this, Nikolai wants something, something a lot less abstract than revenge or honor. Something that worth a lot of money. This is why he showed up in your doorstep after 28 years. Let's go kill Tsina I hope it brings you some closure. Killing her will not bring back your dead comrades nor will it make Vory about honor and family. Vory is and always was about power and money. It will still remain a place of power-play and politics and crime and murder. Honor? Family? These are the methods use to keep a bunch of butchers working together, instead of killing each other. I'd do it the same way if I was to lead a gang."
