[Fate type Redline] {chapters 1 to 6} (Discussion)

I question how time travel works again in the Fate Franchise. I thought Fate's Time Travel logic works the same as Marvel where anything you do in the past doesn't change the future, and you only create an alternative timeline if you change the past; hence Emiya Archer's idea to kill his past version was considered useless. Obviously the story is using "Back to the Future" logic when the main character's existence suffered when his grandmother was attacked.
