Be made put immediatly a target on your back by the Feds,risk more harsh sentences instead like said Frank Guerra a Colombo associate "they know who I am in the streets,I dont have to prove nothing" plus you can easly decide to leave the life. A well redpected associate can beat a made guy in a sit down because count the money not the brutal force.
But as a simple associate,the others dont have to ask the ok to kill you.
