"Corruption is like a ball of snow, once it's set a rolling it must increase"

This quote by Charles Caleb Colton is a metaphor for the insidious nature of corruption. It recommends that when corruption has been introduced into a system, it will continue to grow and spread like a snowball rolling down a hill. The snowball will become bigger and bigger as it gets more snow, and likewise, corruption will become more and more pervasive as it is enabled to continue untreated. The quote indicates that it is essential to do something about it against corruption as quickly as it is spotted, as it can quickly become a significant problem if left untreated. It also acts as a warning that corruption can be hard to remove as soon as it has actually ended up being entrenched in a system. This quote is a tip that it is necessary to be alert and act versus corruption prior to it has a possibility to take root.
