Playing With / Morality Chain

Basic Trope: Character is only reason that another character remains good.
  • Straight: Alice keeps her older brother Bob's nastier side from surfacing.
  • Exaggerated: The only thing keeping Bob from gleefully skipping across the Moral Event Horizon is Alice.
  • Downplayed: Alice keeps Bob from being an aloof and condescending Jerkass.
  • Justified:
    • Alice and Bob have Twin Telepathy and Alice is an empath. She routinely sends Bob positive emotions to keep him in check.
    • Bob had a very traumatic upbringing, and as a result hates everyone and everything except for Alice.
  • Inverted:
  • Subverted:
  • Double Subverted:
    • Well, that's what it seems like at first, but he actually becomes brutal and obsessed with vengeance.
    • After failing to convince Bob not to burn down a church, rob a bank, kill a priest and kick a puppy, she manages to convince him not to jaywalk.
  • Parodied: Bob is a psychotic, Spikes of Villainy-wearing Sociopathic Hero who turns completely harmless when Alice is around, and Alice refuses to believe he's anything else.
  • Zig Zagged: Alice's presence prevents Bob from committing evil deeds half the time; it has no effect on him at other times.
  • Averted: Alice's presence has no particular positive effect on Bob's behavior.
  • Enforced: The director says he can't see why Bob is on the good guys' side when he's much meaner than any of them, so the writers add Alice to give him a reason to stay.
  • Lampshaded: "Now that the meddling fool is out of the way, I'm going to kill you!" "Bob, what are you doing?" "Crap, Alice is back! For some reason this ruins everything!"
  • Invoked: Alice was deliberately raised to be her brother's keeper and balance out his bad side.
  • Exploited: The heroes set Bob up with Alice in order to keep him under control.
  • Defied: "What, you thought I'd spare you because my little sister was around?"
  • Discussed: "I always feel like Bob would kill us the moment our backs were turned if Alice wasn't around."
  • Conversed: "He's one of those characters that only stays good because his sister is watching. I bet they'll kill her off or something eventually so we can see him really snap."
  • Deconstructed: Because she has to keep Bob in line all the time, Alice can't live out her own life and is just as chained to his side as he is bound by her existence. Mutual resentment gradually weakens the bonds between them until something finally gives way.
  • Reconstructed: Eventually, Alice rubs off on Bob; he starts to become a genuinely good person even when she's not around, so eventually, he doesn't even need a morality chain to be a good person.
  • Played For Laughs: Alice keeps Bob in line by terrifying him, despite being The Cutie in all other respects.
  • Played For Drama: Alice is targeted by people aware of how important she is to Bob in order to get Revenge by Proxy.


The only reason I'm letting you live long enough to go back to Morality Chain is my sis, got it? Anything happens to her, I'll kill you, grind you into hamburger, and feed you to your mother, and if you're lucky, it will be in that order.
