2 Works in Darla Dudley & Shazam Family
Darla accidentally Shazams herself back into kid form when they're in the middle of a battle with a villain, and she bumps into Captain Cold, who just so happens to be robbing a nearby bank. Now, Leonard may be a bit sociopathic, but he doesn't hurt little kids. Billy freaks out because he thinks that Darla just got kidnapped.
Dr. Sivana isn't a good person, but he does have a bit of an issue with actually hurting children.
In other words, how Darla Dudley saved the world, one kind word at a time.
