Yes. And they should build large magnificent structures in the middle of dense forests. Find the structure, look around, see them circle you, dead.
Meh, I had an idea like that however they would instead have their own NPC village variation (the other possibly being pigmen or maybe other humans) that would be dark and gloomy and they work in a hivemind and ignore you until you attack one, like the borg.
I also thought about them being able to make traps but then I thought that might just be annoying.
I can't wait for enderman, he sounds actually kind of scary.
*Endermen
There's more than one.
