The consequences of our actions are always so complicated, so diverse, that predicting the future is a very difficult business indeed.

That as a monarch he was quite unfit
But still and all they had to admit
That he loved his mother.
— Tom Lehrer, "Oedipus Rex"
Vaarsuvius: Though I cannot move, I am in no immediate danger. You made the right decision. Now go and meet our attackers.
