I am interested in this topic too. In a recent court decision in Texas USA, a judge defended a very lenient sentence for a kid who killed 3 people while he was drunk and driving. She said:

1. Since his parents are wealthy then he can be rehabilitated.
2. Since his parents didn't teach him right from wrong then he deserves a second chance to learn.
3. Poor people can't be rehabilitated so they should get more serious penalties for crimes they commit.

Also, people can get better treatment in prison if they are sent to a 5-star prison. It works like a hotel. The prisoners pay rent for their cells and can even leave the prison to work.
Do the courts in Russia work like that too?
Are there 5-star prisons in Russia?
