"No treaty is ever an impediment to a cheat"

This quote by Sophocles recommends that no agreement or treaty is ever strong enough to avoid somebody from unfaithful. This implies that no matter just how much effort is taken into developing a contract or treaty, it will never have the ability to entirely avoid someone from breaking the guidelines. This might be analyzed as a cautioning to be cautious of those who may be tempted to break the rules, as they might have the ability to find a way to do so. It might likewise be viewed as a reminder to be careful when making contracts, as they may not be as protected as one may believe. Eventually, this quote functions as a reminder that no matter how protect a contract or treaty may seem, it is still possible for somebody to find a way to cheat.
