NO, not at all!!!
Being a "RAT"(or a snitch) - worst thing can happen to any human. It's better to end up dead than become a "rat" or a snitch.
If a "rat" would go to jail, the same or next day, a "rat" would become a "jail bitch"
You can ask any honest police detective, what do they think about "rats".
Read a History - what have happened to "rats": let's say, during 1937-1939, soviet NKVD "exterminated"(executed) more than 20,000 NKVD "rats" - who needs weak-minded eyewitnesses and who would be able to trust them? Once you've done to someone - you'll do to others...
