Orcs Are Evil.

The basic nature of the universe is kill or be killed, eat or be eaten.  Everything in this universe fights for it's place, from the largest star to the tiniest microbe.  Compromise exists only out of mutual convenience and is often fleeting... 

Orcs will always be evil to me.  I'm not interested in all the nuance, there's already plenty of that in humankind.  Why do orcs raid?  Because they're fucking hungry agents of Chaos and they want nothing more than to destroy the realms of men, elves, and dwarves.  They're not humans, they're not even humanoid.  They're monsters.  The stuff of nightmares.  Do orcs have babies?  HELL NO.  They don't farm and they don't build cities.  They rape and pillage and kill and eat.  If orcs are discovered in the hills near your town, you're in DEEP SHIT -- Achtung! Orcs.   It's like an infestation that has to be dealt with.  "Sire, orcs are raiding up and down the frontier, three villages have been lost!" -- "Muster your knights!!!"

Imagine seeing the remnants of an orc raid where it's clear the villagers were cooked and eaten.  And God knows what's happening to any that were taken alive...  The stakes are so much higher now aren't they?

Comic series from the 80's when orcs were like giant hogs.  Their image has since humanized and become more ethnic over time, which is partly why we are where we are.

   The Realm was classic D&D.

And then there are the subterranean, spider-demon worshiping, human sacrificing, slavers.  No, that's not evil.....  What if they were albinos?

Anyway, it's your game play it your way, whatever way that is.

The rest is noise.

Game on.
