Redemption
Redemption is one of the oldest themes in storytelling of all kinds, including film. At least in part, this is because each of us can relate to the emotional need to make up for our mistakes, be vindicated after a false accusation, or heal a breach between those who ought to love each other. Redemption occurs when a character, group, or other entity experiences one of these things. For instance, in Harry Potter and the Prisoner of Azkaban, Sirius Black is redeemed from his reputation as a mass murderer (at least in the eyes of the protagonists) when the true facts about Peter Pettigrew come to light. Other films show that he never receives this same redemption in the larger wizarding community until after his death - a fact that makes the death more tragic. In the last film in that series, Draco Malfoy - a series long villain with a long family heritage of darkness - is redeemed when he chooses his exiled family over Voldemort. His family shares in some of that redemption, though not all of it. This treatment of Draco is in harmony with a belief among some filmmakers (and other storytellers) that it is unethical to not redeem a child villain. Think back on the films you know with children on the side of evil. How often is it shown at the very end that the child has been misunderstood, abused, manipulated, or coerced? In other cases, how often does the child have a change of heart and end up surviving the disaster? This is because storytellers do not wish to say that mistakes made as children make people permanently bad and worthy of destruction. This same service is often done even for adult villains for much the same reason.
Of course, some filmmakers do not share this belief. The Hunger Games is full of brutal, openly vicious or evil children who get what they "deserve" by dying violent deaths at each others' hands with no redemption in sight. There are a variety of reasons for doing this in a story, from an attempt at "realism" to a desire to take the implications of a story to its most terrible extreme in order to make a point. But to get points for this card, your film must include redemption as a theme.
