Yeah I guess regular intuition only cover affecting the present and future. With time travel it might not be taken for guarantee that the past “is in the bank”. I mostly took the role of the grandfather to be your causal support. One can consider whether things would change if “kill grandfather” is changed to “kill you just after having been born” (or to the more extreme end “snuff out sun before life develops on earth”).
What about your grandfather?
