So Rembrandt's ambition is pretty much to become the largest company in Tsilge.
He's already a lover with Lisa, his current wife, even before the previous president of Hanza's company died.
Then he killed, through Moris, the previous president and (kinda) blamed the craftsman for that.
Then he dispel the blame to gain trust of the craftsman.
Then he "seduce" the Hanza's current president, the previous president's daughter.
Then he finally killed her to absorb the Hanza's company into Rembrandt.
That's why he's kinda disappointed when the craftsman gives up on the Hanza's pres, since if the craftsman keep his love burn strong, he might be able to absorb Hanza's company even quicker since the craftsman already trusted him.
That's kinda fucked up, and makes the craftsman grudge justified.
So why'd he even "seduce" the Hanza's pres, again? Like, he doesn't need to console her right after her father's dead, and she'll stay as the craftsman lover and get absorbed into Rembrandt way quicker.
Or why'd he even frame the craftsman for the prev Hanza's pres death, anyway. If he just killed him "normally" and bless the craftsman's love through normal means, he can reach the same thing with less blood.
