It was a cannon event Template

It was a cannon event. When something terrible is happening and you let it happen so that the universe is not destroyed by you preventing a small terrible thing from happening. Like the death of a relative. It's from the marvel spider-verse 2 where Miles Moralis is told not to prevent the death of his father. This is in order to prevent the destruction of the whole universe which inevitably leads to the destabilising of the multiverse.
