Full marks to young Mr Grayson there for standing up to Batman and telling him he's being an idiot.
To be fair Batman's act in mindwiping him and depositing him in an orphanage are dickish in the extreme, but bear in mind it took time and effort to do it, whereas quietly breaking his neck and burying the body in the Batcave would have been a LOT faster and more efficient. That shows he cared... sort of... dysfunctionally... doesn't it?
