Virtue is, when you look at it very closely, that which is after all most expedient.
Often we manage to not merely justify our questionable actions but cloak them in a "moral" veneer.
It's seductive and easy to pretend that we are in the right. And it is very easy to come up with a gazillion justifications and excuses and then proceed to do what we wanted to do in the first place.
But, for once, let's not.
The right thing -- here and now -- is the one true alternative.
And self-delusion is only a postponement of responsibility.
