Are there any rap or rock songs about killing or beating up bad people (drug dealers, rapist, pedophiles,etc.)?

Both have a 90% chance of being a repeat offender of the same or similar crime.. both are vile with very little success rate even with rehabilitation. That's why there is a sexual predators list online and they are supposed to register so the community knows where they are.

Rapists, without a doubt. It's rather strange that you would even have to ask, unless perhaps you are confused about the meaning of the word pedophile.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
