Nah he's obviously smart and cunning (in a good way)
I think he just have difficulties to open up and be honest, maybe a trauma or something. We'll see later in the story maybe.
His little sister is probably dead and maybe his parents are too.
He was just doing whatever without a single thought of the consequences, probably hoping someone would end him.
His reaction to her hesitating about saving him shows that he genuinely wanted someone to save him from himself.
