Titus 1:12-13

One of the Cretans even give a poor testimony against Cretans, calling them liars, evil beasts and lazy gluttons. As a result, Paul affirms this testimony and encourages Titus to rebuke them sharply. Perhaps Paul needed to add this to add legitimacy to what he was saying. Perhaps it was hard to believe that Cretans were like this. However, it is important to call something what it is, instead of deceiving yourself into believing it to be something else.
