Newlyweds who lost limbs in the Boston Marathon bombings two years ago are saying Dzhokhar Tsarnaev, the man convicted of perpetrating the blasts, should be spared the death penalty, reports The Boston Globe.

Jessica Kensky and Patrick Downes, in a statement published by Globe, say “[W]e must overcome the impulse for vengeance.”

They add, “Under our current justice system, we believe that the best way to move forward and achieve our goals is a life sentence in prison without the opportunity for parole or appeals. It is time for us to invest our energy and resources in the future instead of in the past.”

The sentencing phase of Tsarnaev’s trial is scheduled to start Tuesday.
