Song that conveys a specific theme.?

I have to do project for english class where I find a song that conveys one of the following themes and make a multimedia presentation for it. Only problem is, I can't find a song. The choices of themes are:

-People should not allow their amibitions to rob them of simple pleasures in life or to come before relationships with people they love.

-People must stop persecution when it first starts or it will only get worse, and when it spreads, it may be directed at them.

-The pure love of a child can be a person's salvation.

-Wrongdoing carries its own punishment, just as doing right has its own rewards.

-People are not meant to be alone; it's hard to survive, let alone thrive, when we are isolated from our fellow man.

-Love and determination can overcome the most difficult obstacles.

-The best intentions of good, noble men can lead to tragedy.

-Language is a powerful weapon, and in the hands of a skiled person, can be used to manipulate others.

-Violence and bloodshed can never have morally good results.

I'm thinking maybe "Hero of War" by Rise Against for "violence and bloodshed can never have morally good results"....but idk.

Thanks.
