MC is covering for criminals and helping them, which makes her an accomplice or a criminal. Florian was unprofessional (giving out his phone number and offering a cuddle while he was still (just) a student intern) and sometimes manipulative. However, he helped MC get rid of José and Emily without isolating her from her other social interactions: Cain, Abel, and the two girls who went to London. Florian is by far not as much of a red flag as MC, Cain, and Abel. But he is always the only guy that is punished :/ .
Cain was orphaned then adopted by abusive racists who killed his older brother, and Abel's family burned to death. I'm sorry you don't think they've been through enough.
I guess I just don't understand why you're commenting as if the game doesn't make it clear who these characters are. No one here is a fully "good" person, and I am willing to bet Florian has his own share of skeletons in the closet. I just hope you're not upset when it turns out that he's just as fucked up as the other two. The story isn't even halfway over yet afaik from the youtube interview, so we'll see.
