Revenge

Marcellus wanted no apology - he only sought revenge ("Mid-Evil "(Medieval) style).

"Success is the best revenge." - French Proverb
"Success covers a multitude of blunders." - Bernard Shaw
"Success is a ladder that cannot be climbed with your hands in your pockets." American Proverb
"Success is often the result of taking a misstep in the right direction." - Al Bernstein

In not asking for an apology - I'm just saying that it wouldn't be enough.
Racist people hate a successful minority more that a failing one.
The successful one weakens their argument of superiority.
The failing one can be seen as confirmation.
The success of one seen as being less than themselves just eats at them.
That success is like an incurable Cancer that takes away his strength a little at a time - until he is dead.
Maybe we should focus on the best revenge and let the convenient apology go.
