The Marvel Cinematic Universe (MCU) generally tends to steer clear of directly showing its superheroes killing villains, especially in a premeditated or deliberate manner. This is often to maintain a more family-friendly tone and uphold the moral ideals of the characters. However, there have been instances where villains have met their demise indirectly or through circumstances beyond the heroes' control. The approach to handling such situations often aligns with each hero's moral code and the overall storytelling direction of the MCU.
