The power of Lale’s bag is noteworthy, since it symbolizes the protection afforded to him by his new position as the tattooist. Unlike the average prisoner (who is in constant danger of getting harassed, beaten, or killed by SS officers), Lale has at least a small amount of protection. And yet, Baretski is quick to point out that Lale is not
completely safe, especially from him. By saying this, Baretski effectively keeps Lale in a state of uncertainty, forcing him to continue going through his life in fear.
