A mad man

Tope says:

He scatters every place
with his trouble and craze
his memory of sanity all erased
he doesn't back down when fazed
his only nemesis is a whip, a cane
in his mind, only insane thoughts reign
a mad man filled with malaise
at the least things, his voice will raise
his mind is an unnavigable maze
of sanity or sincerity, he bears no trace
he cries within himself and giggles outside
the dimension of his madness,so vast,so wide
as insanity's stallion gives him a jolly good ride
