No one has the fortitude for whacking a rat. The mob is just a microcosm of society and just like society in general, their only concern is the next nickel. I'm not advocating killing anybody, but once you choose that life, you are either committed or you aren't...and by allowing these guys (rats) to remain living, especially out in the open, normal lives, it just makes a mockery out of what once was a way of life, not just a means for earning.
