I have a book. And I offer to you to read it. Ofcourse you are curious what it says.
The book contains only one page and it reads:
"Who ever reads this, has to kill another person who has read this page, but who has refused to kill a person. There are plenty of them around since a lot of people have been reading this text and some have killed after that, but plenty have refused. Ofcourse when you've killed the person, you are free again to do what you want and will not be on the hitlist of some next person who reads this text. But if you refuse to kill, others are allowed to kill you."
Are you going to kill as ordered, or will you refuse?
You are ofcourse allowed to explain your answer. For example how did you feel after reading the book.
