Yeah, betrayals and breaking promises are about as human as you can get. Maybe it's necessary if you find out later in the game that someone or something aren't doing exactly what you signed up for, and in some cases, it may be for the better to go back on your word. Still, it really shows how untrustworthy humans can be, so I'm with the researcher there on disliking humans if she wasn't up to something with that phone call at the end there.
