Mr T says :

It is never EASY to balance responsibility with ETHICS.

As a TIME LORD you enjoy certain privileges BUT with those opportunities COME great responsibility and ultimately only you can MAKE that decision.

I am sending you my leaflets GENOCIDE FOR THE GREATER GOOD and 20 WAYS TO LOOK IN THE MIRROR IN THE MORNING WHEN WHATEVER YOU DECIDE TO DO WILL ULTIMATELY RESULT IN THE END OF UNCOUNTABLE LIVES.

BUT if whatever you decide to do results in putting FIREWORKS IN MY BINS and deliberating about BLOWING THEM UP you will travel in time the hard way, when I punch your face into the middle of NEXT WEEK.
