The always-controversial Sean Penn draws criticism even when he's at his most charitable. Now, according to the Huffington Post, he has a few choice words for critics who have insinuated his volunteering in Haiti may be an effort to beef up his profile.

"I guess I've been so away from it all in our tent camp in Haiti that I haven't had an awful lot of time to pay attention to them," he told CBS News in an interview set to air on the upcoming 'Sunday Morning.' "Do I hope that those people die screaming of rectal cancer? Yeah. You know, but I'm not going to spend a lot of energy on it."

Penn has made two trips to Haiti since an earthquake devastated Port-au-Prince in January. TMZ reported last week that Penn was personally responsible for saving two individuals trapped in the rubble of a collapsed building.
