Fear not the paradox is, paradoxically, not going to happen.
I think time paradoxes don't exist - they're just a sci-fi idea... cos, if every decision, even down to the quantum level, creates a new alternate reality then....
Israeli scientist creates time travel.
Mossad think it's fab opportunity to convert the planet to Judaism.
Chap travels back in time and meddles.
Chap has now create a new 'spur' of reality at the point of devious meddlesomeness which means he's now careened off down another alternate rabbit hole in which he came back from the future to meddle.
Original timeline is secure, he's just now created a new one in which he can move freely back and forth but it's separate and distinct from the timeline he spliced himself from at the point of meddling (likely at the point of his departure in that original 'present' when he pressed the GO button on his time machine).
So the dodgy time-traveller has actually irreversibly left his original timeline/causailty-stream and created a new alternate one by his own actions in which he's now trapped, i.e. he can't 'undo' his own time travel to revert to where he used to be as he can only go back further into the parent of his timeline, creating further splices which may or may not work out more like the original one he left behind.
Hence we don't need to worry about temporal paradoxes, happily.
