Crow might ... but it would very much depend on my client. Now since I don't know you IC, I doubt he would be persuaded by the ammount of money you offer. He would even be weary of that ammount by his own clients at this point.
If I was playing a black caste, I would not take the job, I might axe off others, but I would draw the line at children, even if it meant banishment from caste and having people coming after me to ensure my death, I still wouldn't take a hit on a target that wasn't even a legal adult.
We are talking about 100 gold that is a fortune so I think the killers would do it.
that brings the next question when would the kill be good ? when the child is 16 ? What is the child is 13 and looks like 18 and you don;t know the age? or is it pure that the child not even 2 years old ?
You have to put it out of the RL mentality and in Gorean Metality and then of a Killer, one that is hired to kill.
