1. Todd was changed very much, cause in the beginning he was so shy to come out. Then Mr. Keating had got Todd and made him stand up in the class and tell him to forget about everyone else  and let the poem speak to you.

2.Cameron did not change throughout the movie. He talking and blamed everything on Mr Keating and spoke out about everything.

3.Mr Keating is his own independent man. Mr Keating does not change throughout the movie,with all the negativity looked at him, does not affect him. One thing he did change was to know when to stop, as for Neil and his father it was just not his place to speak and give Neil that advice. So after that he learned that he can not try and change people that follow by rules etc.

4. Todd Anderson had to overcome his fear of coming out etc. Neil Perry got help from Mr Keating to talk to his dad, and to tell him how he really felt. Knox Overstreet overcame himself to talk to his crush. Charlie overcame his ability to not be ashamed for expressing himself. Todd was the main character that changed throughout the whole movie at the end he was the first boy to confess to Mr Keating and stand on the desk to show his respect. He overcame his fear in help from Mr Keating but also Neil, he would talk to him and try to get him out and just come hangout with the boys. He did not fail as you saw in the ending was the first guy to speak the truth etc.
