It's super easy to think of what you could or should have done. A lot of people live with regrets and what ifs. IMO, I think that's mostly why a lot of people are somewhat interested to change their past.
sure life is short on Earth, changing the past is actually a pretty good idea. Only though if you really know what went wrong in your life, so many people are still delusional about causes to the problems they have. Usually a character defect or something.
Changing your past in that case is a horrible idea and only makes things much worse. If truly aware of went wrong then it's a fantastic idea. Why not? Obviously god and reality makes it doable so yeah it's a wonderful blessing.
Actually millions of people who are self aware of what causes their problems were to change their pasts the world would be heaven. Changing your own past for the better always changes the pasts of other people for the better too.
If you change your life for the better now responsibly you change 100's of people's lives for the better too. yay.
can't think of a more efficient way to change the entire planet immediately.
I think time travel is a divine right for ethical people. Is this the real reason why suffering on earth exists at all? immorality with time travel?
Better question; is immorality with time travel usage the reason why earth is hell? Can't imagine a worse way to screw up the planet...makes ya go hmmm.
how about using the ultimate power of the universe(time) and doing it to all children today, in every time period of the past in the future and on all other planets. That is possible with time travel with one person doing it. Takes a lot of work but is doable.
Here's a mental exercise. Name one object or energy that doesn't have duration(time)?
is everything time? Light has duration, matter has duration, EM fields have duration, etc.
Is God time?
Greatest sin Lucifer did was to try to ursurp God himself.
