some friends abetted that who will consume more whitener erase ex bottles without loosing it? during this wrong doing one abettor died.Is it crime?

You have not presented me with enough information to make a determination whether a crime has been committed or not, but depending on where this occurred and what type of influence was placed on the friend who died, there could be civil liability.  This sounds like a stupid bet that ended in a horrible tragedy.  Kids need to understand the dangers of huffing or otherwise ingesting harmful household chemicals.  I am saddened for this family.
