That was an interesting read but Existensialism kind of clashes with the WoD.
The WoD is filled with supernatural creatures that prey on humans on way or the others. It is even arguable if a human being or even a vampire always have to feedom to actually make a choice.
Think about it with stuff like Dominate, the blood bond to cite the vampiric side of it. Not to mention for vampires the Beast hinders one freedom pretty badly.
Can I really be held responsible if my beast took over and slaughtered people ? It was not MY choice afterall. And in V5 this is even more prevalent as the beast can intervene without necessarily falling in Frenzy.
Then there’s the stuff about how we are shaped by our elders especially our antideluvian. You can be the calmest man in the world but since you were embraced by the Brujah you WILL be angry cause Brujah was an angry person.
And that’s without entering the conspiracy stuff that every kindred has real free will and is just a pawn to his elder in the Jyhad. That’s of course wrong and antideluvian don’t exist.
