Ya.. I don't feel horrible about laughing at the jokes told about him at the Roasts, nor should anyone. That is what a Roast is. Everyone who gets made fun of at these roasts takes all the jokes in good humor as did Patrice. If you think that Patrice was offended or pissed off by any of those jokes, than it seems you may have missed who Patrice was as a comedian and a human.
Friends will rib friends, and I'm sure today everyone who made jokes at Patrice's expense at the Roast are feeling terrible, but not because they told hilarious jokes in the proper context, but because they lost a colleague that they respected enough to make those jokes about.
