I believe you meant is that what is deemed to be greed is subjective. Everyone can have opinions, even wrong ones.
The concept is objective but its application is mostly relative.
Dak is seen as "greedy" because it can be argued that he demanded more than what he is worth and this will cost the rest of the team - and by extension the fanbase - in a desired goal to win championships. No one would complain that Dak paid $60 million a year if he was a significant component in helping the team compete for SBs, e.g., like Maholmes or another "elite" QB, instead of being a detriment to the process.
