Oh, bring him back alive. Make him suffer--and spill his guts--before dying.
As much as that sounds rewarding, bringing him back alive means we'd have to spend money feeding and clothing the murdering bastard until such time as the civil rights lawyers, who wanting to make a name for themselves, work to obtain his freedom. Now how the forces that capture him want to kill him my feeling is "feel free to do whatever you want". Just don't bring him back alive.
