Throughout his career, renowned director Martin Scorsese has explored a wide range of topics and made many contributions to the film industry. Violence is a topic he frequently explores, as seen in a number of his films. However, Scorsese no longer feels the need to continuously prove himself through this portrayal because his reputation and influence have grown over the years.

One could interpret Scorsese's earlier work as an effort to investigate and comprehend life's many facets, including its darker side. Scorsese employs violence in his films to depict complicated human conditions, including conflict, power struggles, and societal issues, much like a painter might use various shades and hues to convey emotions and narratives.

But Scorsese's body of work has grown over time to include more than just these powerful depictions. His varied projects demonstrate his depth and adaptability as a storyteller. The necessity of merely portraying violence waned as he grew up, both personally and professionally. His later writings exhibit a wider variety of themes and storytelling devices.

Essentially, Scorsese's remark shows a change in his artistic priorities and a maturation in his understanding of his function as a director. It's similar to an artist who has perfected their craft but keeps experimenting with new forms and expressions, unrestricted by the original instruments or aesthetics that brought them fame.
