I wouldn't call it "rape," but it is pretty much evil, in the way that Hill did it. Not that this is anything new, since the entire basis of her character is that she believes civil liberties are for pussies ...
Non-consensual mind-reading is always pretty dodgy, but what makes it a quantum leap of worse with Hill is that she resorts to tactics like that as a FIRST resort, and indeed, if you look at the way she treated Peter, for all of her "I don't have time to play games" bullshit, she very clearly extracted information from his mind in the most painful and humiliating GAME-PLAYING way possible, for no other reason than to assert her dominance. She WANTED Peter to know that she'd ripped the information from his mind, and she WANTED it to hurt him, or else she would have had her psychic take the information from his mind WHILE HE WAS UNCONSCIOUS (because really, WHY would she need him awake, when he'd be putting up LESS RESISTANCE while he was asleep?), and she wouldn't have wasted time TELLING HIM WHAT SHE'D DONE AFTERWARDS.
