Heard about Valerie Solanas. Now I have an itinerary should I ever rewrite history:
- Decapitate Valerie Solanas
- Decapitate Hitler
- Stop Lee Harvey Oswald
- Save MLK Jr.
- Save the Library of Alexandria
- Pre-emptively destroy the religious chokehold on Europe, ending the dark ages
I would just go back further. For example, you might decapitate Hitler's grandfather instead.
