* Horus - In Egypt, in the Heb-Sed festival, the powers of Pharaoh
(Horus incarnate) were tested. If found weak, Horus was expected to

This Quran verse is often quoted out of context. The preceeding Quran verses inform us there was a war treaty between the Muslims and pagan Arabs, which the pagans of Arabia broke.
Therefore this verse applies to a very specific historical event and applied only to those who broke the agreement.
Naturally, in war violence is expected. If country A declares war with country B because a peace treaty was violated, then both countries will expect their soldiers to kill or be killed.
