According to The
Doctor’s Wife, the TARDIS would always take the Doctor not
necessarily where he wanted to go, but where he needed to be. With
that in mind, it might be fair to assume that she was in some really
sadistic moods at times, because there have been some occasions where
she has taken the Doctor and company somewhere it might have been
best they hadn’t landed in the first place.
No matter the
incarnation, The Doctor has always spent his or her time travelling
the universe in an attempt to right the wrongs they encounter, but
there are some scenarios where even they can’t save the day.
Indeed, in some rare cases like these, they do tend to make things a
lot, lot worse. Sometimes taking the mantra of never be cruel and
never be cowardly can backfire on the Time Lord, other times their
curiosity can end up being the cause of a lot of unnecessary death
and destruction, on occasion including the Doctor’s own, and in
certain circumstances, they were just a plain idiot.
