Doctor Who: 10 Huge Problems Nobody Wants To Admit About The Doctor

9. CONSTANTLY Breaking Time Travel Code

Perhaps some of those dire consequences of the Doctor's adventures could be avoided if, say, there was a code in place to stop people treating time travel like a game?

Oh wait, there is.

The Time Lord non-interference policy exists to prevent the potentially disastrous effects of time travel on the wider universe, and yet the Doctor treats it as flippantly as dinner table etiquette. 

Sometimes (usually when real world history is concerned, such as the eruption of Vesuvius or the Partition of India) they will adopt the Time Lords’ policy of non-intervention, insisting that events are “fixed” and cannot be changed under any circumstances.

Then in the next breath they’ll go and land in Isaac Newton’s back yard, marry Queen Elizabeth or just casually bring Vincent van Gogh to an exhibition of his artwork in the present day.

Stories like The Waters of Mars and Hell Bent do call the Doctor out for going too far, but most of the time they’re given free reign to pick which points in time are fixed and which aren’t. And when they do the exact thing they’re constantly telling their companions not to do, they just end up looking like a massive hypocrite!

We've seen the Doctor almost tear New York apart and very nearly unleash a plague of Reapers, among other things. It's almost as if those time travel laws exist for a reason.
