Pinchas acted in what seems to be a violent manner. However, the pasuk testifies in the name of Hashem - בקנא את קנאתי - He was zealous for G-d only. It had nothing to do with his own personal feelings. He was in fact the grandson of Aharon who was a lover and pursuer of peace. More light can be shed on this matter here. Unfortunately, recently [maybe due to my excursion the the US and other things occupying my mind] I have had a dry spell in writing articles in Lashon Hakodesh. May Hashem restore my lost glory and I be able once again to write holy divrei torah in His holy tongue on the holy earth of Eretz Yisrael... AMEN!!!:-)
