Sheer madness

What do you call something,
That you do when you know,
Failure is inevitable.

What is the name for that?

It needs bravery,
Combined with a huge dose of madness.

And in the combined mess,
Erupts something, called bravery.

It blinds you,
You are no longer you.

You run fast,
And bump yourself into failure.

That is bravery?
No.
What you did was insane.
Erupted out of sheer madness.

And,
Does failure hurt you now?
It ought to.

You knew it before that you will fail.
So, it ought to hurt less!

On the contrary,
It hurts more.
