Victor couldn't stop pacing up and down his room. He told himself that Arianna's well-being was none of his business and she deserved whatever came her way for pissing Marcel off yet he couldn't help but care.
No, he didn't care for Arianna, rather for Marcel who might lose his soul and turn out to be way worse than his father if he continued this way.
Marcel was better than his father but it didn't erase the fact that he shared his bloodline that could easily turn him into a monster. And Arianna might be that final straw.
If Marcel couldn't endure the girl's tantrums and had her killed, what's to say he wouldn't become a tyrant.
Victor loved his cousin so much and that was one of the reasons he worked hard to be his consigliere when he had other careers - that was even crime-free - to choose from.
