Actress Ellen Page: I’m A Transgender Man Named Elliot

1) History, law, and even morality are as dependent on their mistakes as they are on their shiny bright moments. Reforms and wise changes more often rise out of massive mistakes and near misses. Sometimes it takes doubling down on a mistake for the reform to stick. After WWI, many foreign policy thinkers came to believe taking any land by war was wrong. They were ignored by the Big 3 (France, Italy, & UK). After WWII, everyone pretty much agreed, no more conquest.

2) If you actually had the ability to time travel, killing is the least imaginative way of solving a problem. For example, what if a wealthy Jewish friend of the Hitler family paid for Adolf to go to art school? There is another wrinkle in the morality of killing with time travel. Basic rule in physics and sociology, by observing an event, you change it. The change more often is small, but if somethings on a knife's edge, it can be the decider. If you tell someone they are going to commit a terrible crime, they might not do it. A lot of people who collaborated with the Nazis would never had done the extreme things they did at the start. A warming would have either slowed them down or made them reverse course.

3) If we ever did charge people with crimes they would/might commit, we would have to take into consideration that the crime hadn't happen. Some might argue that murder would be reduced to attempted murder. I would go further myself, but I'm a Blackstone Principle extremist. I can't in any circumstance justify 5 years for anyone using Pre-Crime evidence. Maybe they would have to actually commit one real crime before being able to be arrested. Example: I'm going to high and have a bad reaction, and kill a bunch of people. So I get arrested after I buy the drugs.
