Does responsibility exist?
"Deserving" doesn't exist and some would argue that responsibility is the status of morally "deserving" something due to one's moral "obligations" (e.g. that responsibility = a parent grossly neglecting their child is not fulfilling a moral "obligation" and therefore morally "deserves" some kind of punishment).
Did Oskar Schindler for instance have some responsibility during his lifetime or was it all a question of free will and choice?
"Need" is just a fiction. As is "should", "must", "value" and "importance".
