Oh I don't know, I think they could convey it adequately enough. Just imagine.

The shadows gather.

Scarabeus peers around the area, acknowledging all around him except your presence.

Scarabeus whispers 'How these mortal creatures and their pathetic whimperings over the most trivial of matters continue to prove allowing their continued existence is a mistake.'

Scarabeus wields the Sword of Perdition.

Scarabeus whispers 'The Dark Dream was wrong to leave these whelps to their own devices in our world, instead of simply excising them from Thera.'

Scarabeus grins with malicious glee as he now focuses his gaze upon you.

Scarabeus deals a blow of deadly force!
Scarabeus's unholy power does unspeakable things to you!
You have been KILLED!!

And yet, the player would probably find the interaction awesome anyway, since Scar would do it 1000% better. Scar would probably still make interaction amazing even though he was pissed off at you and CF in general. How messed up is that?
