Should I Press the Button?

If i was presented with the option of destroying all sentient life, then would i press the button or not? The anti nacelist view is that we have here a conflict of rights. Just as i dodn't have a right to kill the one person, i wouldn't have the right to to kill all the others. And so you kind of got a situation whereby if you don't, you know somebody is going to violate some one else's rights. But then the question becomes the nature of when and if we can override a rights,. which isn't necessarily kind of a question that's specific to anti natalism.
