I can understand a bear will see you as walking food in certain parts of a world. Wolves won't attack you if there is other game around unless you're near a den. But it's traditional in role play to make them four legged mooks.
But what are we going to do? Turn gaming into yet another politically correct animal rights forum?
Is the non-gaming world awash in "politically correct animal rights forums"? Animals are still treated pretty badly a lot of the time, even if much of it takes place under the radar.
Yet you shove mercenaries out windows without a thought.
Actually I didn't shove that guy out the window. But in general, I'm starting to grow wary of mooks in games, or at least in games that aren't centered almost exclusively around combat in the first place. Aside from whether you think it's excessively violent or not, it's definitely not very logical. In the Mass Effect games, for example, most of the bad guys - aside from obvious non-thinking exceptions like husks, mechs, and drones - should at some point either surrender or try to ambush Shepard's squad in greater numbers, rather than continually throwing small groups at them after it fails and gets them killed the first 10 times. It also leads to characters like Harkin - who, while he may be a scumbag, is not an idiot - deciding to try to have a Spectre killed at sight rather than finding out why Shepard is there before starting a pointless fight.
