Rashi (from Yerushalmi 10:2): You are caught like a fish. You slandered them - you must kill them! Malbim - "Yad ha'Edim Tihyeh Bo va'Rishonah Lahamiso" (Devarim 17:7). 1
Radak: Also Doyeg was his name. The second time this verse mentions him, it is written and pronounced Doyeg; however, in some texts also the latter is pronounced Do'eg, for usually he was called Do'eg. It seems that the latter time, when it discusses killing them, he is also pronounced Doyeg to worsen his name.
When Beis Din executes, the witnesses perform it. Sha'ul accepted Do'eg's 'testimony', and killed them for being Mored b'Malchus. It was appropriate that he kill him. (PF)
