Should we expect others to grow as leaders?

No. Not everyone is happy as a leader. Being a leader brings a lot of responsibility and a lot of decision-making, it is not fair to expect someone to take this on just because we want to. Expecting someone to become a leader is the same as expecting someone to be a doctor or a policeman even if they don’t want to or like it; we can’t expect and pressure someone else to be a leader, it isn’t fair to them. Becoming a leader is a decision that should come from the person itself and not from someone else.
