He definitely was NOT punished enough. He abused a position of trust and obviously caused so much emotional trauma to this girl that it led to her ending her own life.
That girl was so beautiful and looks so happy in those pictures. What a terrible, evil tragedy. There really aren't any words that can describe this injustice.
He'll have much harder time out of prison than in it. As ridiculous as it sounds... He'll never find a job again, and will probably end up homeless on the street and get killed by some gang.
