It is not "reveling", but club comes above players. If he cannot play he should have been let go. Playing a player who cannot cut it (reason doesn't matter) or keeping them on bench, when they ae by far highest-paid in the entire league is criminal for the club.
All the sympathy to Ronaldo, it's a horrible tragedy and our heart breaks for him, but it's no reason for him being on squad.
p.s. Also a technicality, but I would rather describe Ronaldo as "a legend who once played for us" and not as "United legend". He is clearly a Real Madrid legend, who played for a number of teams, ourselves included. Again, not a big deal but still something to mention.
