'course it was an action, that's not really the issue here. 'Action' doesn't necessarily imply 'Gutting people'. The term 'Glass him' is the issue. I am certainly glad that you, good sir, are familiar with all world's languages and phrases but I, lowly dumbbutt, have never heard the term before playing The Wolf Among Us. Something like 'Attack him' or, better yet, a brief way to describe what's about to happen upon clicking the choice would be much preferrable (or even graphical representation - Dragon Age 2 at least had the right idea with putting the little icons next to dialogue options, regardless of how good the game actually ended up being.) I mean, that's the whole point of this whole discussion, eh?
Is English your second language? If so, I could understand how you might be confused.
