Never forgive a rat. They are the most scum there can be.
How would they compare to the murderers, and rapists, from the Italian or, especially Russian rapists within their mobs. Are the clear paedophillic tendencies, related to the Russian or at least Eastern European cultures relevaant?
If you go to prison with a charge for rape, pedophilia or murdering a child you are being put in the opusheniy kasta(downed). These are the lowest people in prison, who are mostly rapists, pedophiles and child murderers. The process of downing goes by raping the person who has such a charge, sometimes they piss on him if no-one wants to get into this homosexual act, or if the person is a strong one, they usually chase him down in his cell for several days until he sleeps and then either rape, piss on him or just rub their penises on the persons lips. There are many more ways how to "down" a person, but these are the ones most often heard.
The same goes to snitches, once you're found out as a snitch in prison, you also get "downed". So, we in Russian criminal culture consider a snitch as an equal scum to someone who's an rapist or pedophile.
The same would happen to a person who would live in a criminal neighborhood. He wouldn't get raped or pissed on, but as soon as some person would find out him being a snitch or being a pedophilia, he'd be beaten to death or tortured before that. Prison this way makes it more better, the person pays for his action trough all his prison term, being raped at the process of being "downed" and even later by other people who were "downed", as he sits in one cell with them. If he shows up somewhere where normal prisoners are located, he gets beaten up and risks being even killed.
There are no such as paedophillic tendencies in Russian or Eastern European cultures, I doubt there is such in any culture on the world. Every ethnicity has their scum and their good people.
