Violence to solve a problem only perpetuates the cycle of violence. Take Joseph Sebarenzi, former head of the Rwandan Parliament. He has endured tragedy most of us cannot fathom.
He lost both his parents, seven siblings and numerous other relatives in the Rwandan genocide of 1994.
Yet, years later, as a senior government official in a position to exact revenge, he instead pushed for peace and reconciliation.
"Revenge is like adding guilt to victim hood," says Sebarenzi. "It solves nothing. At some point, we have to ignore the past and envision the future."
