Harry is a much-loved son and grandson. Whoever his father was/is doesn't alter the fact that he's a member of the Royal Family in their eyes. As such, he must be prepared to modify his behaviour to some extent to conform to what is required by his position. IMO he lacks judgment and fails to realise that even in 'private' he cannot overstep the mark without seriously damaging the dignity of his family. One ought not to forget however that his childhood must have been extremely difficult and the tragedy of the loss of his mother when he was only twelve cannot have left him unscathed.
