How do you get your Succubus Decoction?(Mutagen)

[E|E]

I spared those succubus i met in quest. Now im regretting it. Is there no way to get this decoction unless i murder an innocent succubus just because some humans want them dead?

Although I know this thread is pretty much dead(going in 2 years after release, but I finally got a decent GPU to run it with) but I think most of the people are having two main gripes on this argument about Succubi:

• The succubus in the novigrad contract: I think that Salma is innocent in this case, having alledgedly killed the guards in self defense. I find that guards attacked her out of xenophobia(May I remind you that there are mages and non-Humans burning in stakes in Novigrad at the time?) certainly a better explanation than a succubus that has been living among humans concealed going out of her way just to kill some soldiers that hadn't done absolutely nothing to her. How many humans have scorned or attacked you due to being a Witcher. Imagine that but being considered a monster.
  
  
• The act of killing is not intended in a succubi-human intercourse, and I'm going to quote the Witchers Bestiary on this "Unlike other monsters, succubi and menads feel no desire to kill, do not crave human blood and usually do not, in fact, mean any harm at all. They are motivated by one thing and one thing only: an insatiable lust.".
  
  Now, these men knew exactly what they were getting into when banging the succubi. The succubi do NOT, I repeat, do NOT manipulate their prey mentally, they just seduce them. If they are dumb ♥♥♥♥♥ whose main thinking apparatus is below their bellybutton that's absolutely their fault. Mind you that the only people that have been killed are people that either meant them harm or were too old to withstand the actual intercourse(It's not unheard of inbetween humans, imagine it with a succubus in the equation).

I thought only moral decision here's whether you kill creatures for their body parts :P everything else pretty clear cut imo.
