If I ever joined the army:
"Benny Got Blowed Up" by Nofx.
If I went on a mass murdering spree and was eventually killed:
"Blood Red Summer" by Coheed & Cambria.
If I ever take over the world and become a dictator, but get assasinated then
"So Long...And Thanks For The Crutches" by BoySetsFire.
If I die of a drug overdose and was married/engaged/spoken for then
"The Girl With The Broken Heart, The (By The Way (No One Cares))" by American Eyes.
If I die any other way and am a good person, but was betrayed by everyone except one person then
"Remember To Feel Real" by Armor For Sleep.
Anything else...
"Not A Crime" by Gogol Bordello. Hahahahaha.
Oh, and if I was in the army and in command of a group of people and was a dictator towards them, but ended up being betrayed by one of them and killed and had loved ones at home then all of the above.
