I am a malignant narcissist... and proud of it

Imagine a Button, If you Press it 2 Things happen. 1. One random person in this world dies. Nothing can be related to you, you're untouchable and no one will ever find out. And 2. You get X Amount of Money. At which Point of X would you Press the button? And how often? For me this threshold lies between 100-250$. And I would it probably Press it a few hundred Times and then Stop. Not because i dont want too many random People to die, but because I dont want my Friends, Family or even me to die, and Not an too Important Person because, for example Killing a high Leader or Scientist or other Important Person could alter the Change of the world, means could also affect me. Questions for you: 1. At which X would you Press it and how often and 2. Why would you Stop pressing the button.
