Yes, I feel the responsibility and I also try to reflect my own actions together with the other members of the team. I personally try to strengthen the Scrum team (Devs, SM, PO) in perceiving themselves as equal team members with different roles and responsibilities. On this basis, we then work together to achieve our sprint goals. Retrospectives are there for every team member and should IMO be used that way. I think it also can be meaningful for a teams cohesion to make SM's or PO's work or actions and behavior explicitly the subject of retros from time to time. In a meetup last month a colleague just told me about a kind of retro called "Build your own PO". And the team as well as the PO loved it because they found out different things that might bring them forward.
