The greatest minds in history were all a bit disturbed.

My Roman Empire is how the greatest minds in history were all at least a little disturbed.

Can you think of an artist who never went mad?
A leader who wasn't corrupted?
Perhaps a poet who didn't drown in his words?
Is all the knowledge of this world so heavy, that the more you gain, the fastest you're driven to insanity?

What are your thoughts?
