So the new Vayne story paints her as much more of a corrupted hero
She seems to still hunt monsters, but she also seems to be going mad. It's like the thrill of the hunt is taking over her. She's making unnecessary grandiose, being unnecessarily cruel, murdering her own teacher who was benevolent to her and trusted her.
I think she's very close to going off the deep end, and it gives me a very Bloodborne-esque Gascoigne vibe from her. I quite like it, the fact that not everybody from Demacia has to be good.
. Vayne was pretty much batman. She is obsessively driven to fight the "darkness", she is cold/brooding, but she is not bloodthirsty. She feels it's her duty to fight evil, but she wouldn't murder someone. If she was in a situation where she could either kill the monster or save an innocent, I always thought she would chose the latter "vayne always chooses the latter"(this poor writing made me cringe lol). Of course this new vayne would not only not try to save the innocent, but would kill them herself if she had any reason too.
