Just Who is The Wise Man Anyway?

A change of heart, a change of plan.
Look around, your heaven bound.
And if you like it when you're there.
You'll be allowed to stay.
This is the way it has to be.
A wise man, wisely said.
And so we believed, but some did not.
And though we never knew, the wise man wisely had them shot.

Guess who the wise man is. My money is on a aguycalledbrad.
