Hopefully there are no corporate mercenaries in AvP.

Humans often proved to be brutal and merciless enemies to each others, so I don't have any problem with an "internal racial affairs" additional twist.

Maybe young Rykov will be in the game as a USCM (like in the intro movie of the predator campaign in avp2), and we'll see that Predator pwn him.

meh, scientists are okay.

Predators are not truly evil compare to us. They are evil in the sense they treat humans like dirt ( except for in AVP and the AVP comics. ) Aliens are just animals. But Humans we kill eachother for fun!

Human villains -
Alien - Ash not the main villain though.
aliens - That asshole not the main villain though.
Alien 3 - Some cell members plus Bishop II... and men - not the main villains though.
Alien R. - Dr.Wren , the main villain.

Predator - They fought some guerrilla warfare guys.
Predator 2 - Those drug idiots.

AVP - No one , but some people were clearly not that nice....
AVP:R - The Military and that idiot factory worker Karl.
