Think you have to separate the two. Amuso orders hits but casso did weird shit like killing the guy fixing his house is there a truthful reason casso ever admitted why? They killed fat Pete's uncle probaly cassos call cause amusos in jail. The testa murder. Amusos had more to do within the lcn rules like Salerno was stealing or Bruno might be snitching. theres to many to pic. But the number one murder amuso and casso should have done but couldn't and probaly still be free was killing Pete savino. That could be the number 1 rat that crushed the genovese and lucheses.
