I can understand feeling uncomfortable at fighting an alien race presented as genocidally-minded, but in Halo’s defense, the story shows that most civilian Covenant have no idea about the truth of the actual war, and are misled by the Prophets. And many of the combatants later turn against the Prophets and join humanity’s side, so I don’t think the point it’s true that all members of the Covenant are evil.

But I can understand the bad taste it might leave in your mouth.
