OK it’s late but I was trying to think this through
We all know of the Grandfather Paradox
OK fine, makes sense
But supposing this time traveler goes back and meets his biological grandfather and the grandfather decided to kill the grandson FIRST and actually kills the grandson in the past.
So what kind of problems does this create?
Outside of the fact the grandfather is now a murder and may be arrested. I was thinkin of how it woud effect the future? Or doesn’t it?
