More than 100 students and faculty attended the event in Union Auditorium as part of Honor and Integrity Week.
Sponsored by the judicial branch of student government, the five-day event is designed to increase the awareness among students about the UNC honor system.
The former executive at Brown & Williamson Tobacco Corporation made clear the message that erosion of integrity needs to be ended. "It is not easy to be ethical," Wigand said.
Wigand broke a company confidentiality agreement to expose the harmful way his company was making cigarettes to make them more addictive.
"I had a moral responsibility toward a process that would change a life," he said.
As a top researcher for Brown & Williamson, he thought his job was to make cigarettes less dangerous for smokers and to reduce the effects of second-hand smoke.
He continued his research even as he began to realize that the company was working directly opposite of his goal.
Wigand said he wished he had exposed the truth earlier. "I know I made a mistake. I chose silence -- I was comfortable with silence," he said.
But his duty to care didn't keep him quiet for too long.
