Hazing as in freshman have to carry the bags or run extra or something to me is fine but this seems to have gone well past good natured hazing into abuse
By definition there is no such thing as good natured hazing, as others have said its not optional (that was once the point, a right of passage & you made it thru or were dropped) and it puts the people doing the hazing in total control. As a society we realized that bad consequences from this though not common back in the day were inevitable and the risks/abuse of hazing far outweighed any benefits.
For example Animal House showed how extreme the elite frat Omega behaved & there was a vague allusion to it being sexual, this was a purposeful exaggeration but not far from the mark. Meanwhile Delta had the 'benign' version with kids just getting nicknames (some cruel, mostly funny), and excessive drinking. Yet each likely moved hazing into more acceptable and set a course of escalation where they both eventually became extreme and prone to injuries, accidents, deaths.
Would anyone want their child hazed today?! You'd have to have implicit trust of the hazer.
