Even if the money came from a crime you committed, laundering that money is not the unethical part.

Should a bank robber also be charged with the crime of conceleaing his face on top of the original crime of robbing the bank? It's pretty ridiculous if you ask me 

 No. They shouldn't.  

 Suppose someone robs you, tells a friend, and then asks the friend to help them move the money so that it can't be tracked back to the origin. Is moving the money ethical or unethical? 

 Unethical 

 Should it be a crime?
