Effectively the only context you will encounter orcs in my campaign are violent ones. They have little choice but to attack or plan an attack (unless they have overriding orders) when they encounter anyone they do not consider an ally or someone they can subjugate.Certainly not the way they’re typically depicted. What I like about @Oofta’s take is that it removes most of the unfortunate implications of their classic depiction by making them not an actual race of people, but more like organic constructs. I also like that it acknowledges the possibility that they could theoretically be liberated from the control of their creators. To me, that actually says that kill-on-sight is probably not a morally good policy towards them (and Oofta did say they aren’t actively hunted down). But, most contexts you’re likely to encounter them in are violent ones.
There are other "typically evil" humanoids in my game that don't follow this pattern such as goblins. They have a few exceptions now and then. If you encounter them in the feywild (where they originate) they're typically CN tricksters and not overtly malicious.
