Doctor Odd always makes the right decision.
He also makes the wrong decisions.
He makes every decision imaginable, then he observes the consequences of each decision from his quantum state time displacement chair.
Once he determines the decision with best result, he stays in that timeline.
What happens to the other suboptimal timelines?
The Doctor Odd in those timelines try to shift quantum states into the “good” decision universe.
Because of a near-infinite number of quantum state universes, the “good” universe is overwhelmed quickly.
This is why Doctor Odd destroys the other universes, and his unlucky dopplegangers stranded in them.
