Would you fix it?
Most "Repeating Day" movies, the character doesn't know what's causing the loop and so can't fix it and doesn't know for sure that it will happen tomorrow. This guy knows what's causing it and knows for sure that the day will repeat. If you were him, would you try to fix it, or would you live with it for a while?
I think I'd live with it for a very long time. Think about it. That would be total and utter freedom. You can do any evil, twisted thing that pops into your head, and no matter what, you won't spend longer than till 12:01 in jail for it. Tomorrow, no one will remember a thing. You could do anything. At the very least, I'd spend 20 years training in Karate or something before I tried to stop it. Might as well prepare yourself, ya know?
I wouldn't try to stop it for a very, very long time, if ever. You can always stop it tomorrow, or 500 years from now.
