The answer is: True

Gen 4:15

Indeed, it's true! In Genesis 4:15, after Cain kills Abel and faces God’s punishment, we learn that God marks Cain to safeguard him from other people's vengeance. This interesting twist emphasizes the complex nature of consequences and mercy in biblical narratives. As violent as Cain's actions were, God still sees a value in his continued existence, offering him protection instead of an outright death.

Now, here's an interesting tidbit: while traditional interpretations have varied regarding the mark itself—some suggesting anything from a physical scar to a protective symbol—the mystery behind it piques curiosity. This mark eventually becomes a symbol not just of punishment, but of the potential for redemption. In this century-old tale, there's also a subtle reminder about the prevailing themes of familial relationships, responsibility, and divine intervention.

Also, Cain's story echoes throughout various other biblical references where figures uncover ambiguous marks or demands that reveal much about their circumstances. These narratives remind us how deeply human experiences echo in divine storytelling, marking themes of struggle, loss, and hope. Just like Cain, many biblically-oriented figures navigate a mix of bad choices yet find avenues of grace, illustrating an inherent complexity in the relationship between humanity and the divine. This back-and-forth hints that protection and guidance are always intertwined, no matter our actions.
