Playing With / Morality Chain

Basic Trope: Character is only reason that another character remains good.
  • Straight: Angelica keeps her older brother Damon's nastier side from surfacing.
  • Exaggerated: The only thing keeping Damon from gleefully skipping across the Moral Event Horizon is Angelica.
  • Downplayed: Angelica keeps Damon from being an aloof and condescending Jerkass.
  • Justified:
    • Angelica and Damon have Twin Telepathy and Angelica is an empath. She routinely sends Damon positive emotions to keep him in check.
    • Damon had a very traumatic upbringing, and as a result hates everyone and everything except for Angelica.
  • 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 Damon 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: Damon is a psychotic, Spikes of Villainy-wearing Sociopathic Hero who turns completely harmless when Angelica is around, and Angelica refuses to believe he's anything else.
  • Zig Zagged: Anegelica's presence prevents Damon from committing evil deeds half the time; it has no effect on him at other times.
  • Averted: Angelica's presence has no particular positive effect on Damon's behavior.
  • Enforced: The director says he can't see why Damon is on the good guys' side when he's much meaner than any of them, so the writers add Angelica to give him a reason to stay.
  • Lampshaded: "Now that the meddling fool is out of the way, I'm going to kill you!" "Damon, what are you doing?" "Crap, Angelica is back! For some reason this ruins everything!"
  • Invoked: Angelica was deliberately raised to be her brother's keeper and balance out his bad side.
  • Exploited: The heroes set Damon up with Angelica 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 Damon would kill us the moment our backs were turned if Angelica 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 Damon in line all the time, Angelica 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, Angelica rubs off on Damon; 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: Angelica keeps Damon in line by terrifying him, despite being The Cutie in all other respects.
  • Played For Drama: Angelica is targeted by people aware of how important she is to Damon 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.
