Can it cause a time paradox or is it more like traveling between parallel worldlines?
Anyway, if it's the kind that let you move in space and doesn't teleport you into the ground/walls/outer space because the Earth moved, then I'd go kill some dictator wannabes (oops, sorry to the other guy). Maybe not as babies but as young men, to keep it more fair.

Repeat the process until none remain.
