Is Matt a decent guy? Seems like it--But far from having a "heart of gold" as Dr. Pat claimed. Consider this:

-He knew the name of the porn star--that is one classy guy
-Early on he planned to hook up with Ashleigh--thinking below the belt
-From day one he's been scheming with other housemates--how sweet
-Attended law school--anyone know a lawyer? Do they have hearts?
-He's been around legal professionals so he knows how to put on airs
-Moreover he's completely aware he's going to be watched by America--he obviously wants to come off like a "good guy"
-He mentioned he first wanted to be on this show for fame and money--how admirable

Like everyone, he has some good character traits, some bad character traits, but it is obvious that he wants more than anything else to be admired and honored by other people--if he was really secure in his greatness he wouldn't be so pathetically seeking this validation. It's not like in his down time he is working out ideas for feeding the homeless or making the world a better place--he is just thinking about himself, whether it's feeling sorry for himself or praising himself.

Sorry Joe, you're a decent guy and I wish you the best, but you're still a Schmo.
