[No Loopholes] Survive 24 hours to remove murder from all of humanity.

A god approaches you with a challenge. If you accept and are successful, all intentional murder will be removed from humanity for the rest of time. As this god knows the outcomes of our actions before they ever take place, any behavior which leads to intentional murder will be prevented. If you fail the challenge, you will die and the world will continue as it is and be unchanged.

• To win the challenge, you will need to survive 24 consecutive hours from the time you accept the challenge. You either accept or decline the challenge at the moment the god has finished presenting the challenge to you. You will have no time in which to prepare.
• If you accept the challenge, every single person on Earth will instantaneously know exactly what you look like, what the challenge parameters are, and what is at stake if you succeed or fail. Anybody that does not already know your name, where you live, etc., will not be granted this information. They will simply know exactly what you look like.
• If you accept the challenge, you can rely on the help of others as much or as little as you want.

Do you accept?

Clarification: Since many have brought it up, there is a difference between intentional murder and intentional killing as the first is a legal term and the second is more objective. The heart of the question was to remove intentional killing, and I should have used that verbiage rather than murder.
