He might not be perfect but he has taught Deku wonderfully. Air Force, Shoot Style - not to mention he values and understands the importance of self growth
Wow. There is just so so so so so much to love there. From the beautiful commentary on the human nature, environmental issues, love - to the masterful character writing and overall thematic purpose of the series.
