[@Cu Chulainn] Embracing an established murderer is an exceptionally bad idea. While it seems like vampires wouldn't care about that sort of thing, death is very loud. Going around killing humans is a good way to draw attention to yourself, and using your powers to do it will draw attention to kindred society. Things like that risk a breach of the masquerade, which would likely end up with your character being the target of a blood hunt.

Keeping that in mind; Toreador, as a clan, are more ordered and tend to follow the rules. They're very obsessed with art and beauty, and they also tend to attach themselves more strongly to their humanity. It's going to be something of a hard sell to find a Toreador to sire your character, knowing they're not especially artistic, they already have a disconnect to their humanity, and they make a habit of murder. Unless your Toreador was sired by an anarch, who sired them without permission from the local Prince, it's unlikely the character as you have described them would have been embraced to begin with.

Now, if you were aiming for someone more traditionally artistic and less bloodthirsty to begin with, who after their embrace begins to turn into a killer, then that's far more reasonable. The other option for that character that would make sense would be if, instead of Toreador, your clan were Brujah.

Your second idea seems much more reasonable from the outset, but I'm not entirely sure what you mean by 'director.'
