This meme's born in the famous Facebook page "Il meglio di internet" (that means "The best of the internet"), a page that collect memes, demotivational and other webculture images posted by fans, with a database that contains over 5.000 pics. So, Evil Mario Monti's a photomontage that portrays the temporary Italian prime minister, Mario Monti, such as a malicious person because he only wants to grow rich, don't giving a fuck of Italian problems.
Obviously the meme is sarcastic and all the IMDI users think that the only people who can guide Italy is the economist Monti. IMDI users are totally Berlusconi haters.
