It depends but if your well connected, a good money maker, or been involved in murders or big schemes it would be a lot harder because they would think your a rat but i think if your a respected guy or trusted they would't have a problem letting your retire they would rather have your retire if the family thought you could't handle it than become a rat. You also have to take into consideration that once you get your name in the newspapers,trial or convicted of a crime it would be very hard to find a job thats why the recidivism rates are high among mobsters and also i think with all the heartache in todays mob lifestyle some mobsters still enjoy the money and power. The whole once your in, your in unless you flip or die is sorta true because even if you retire your still considered a made member
