* CompleteMonster: A character that's pure evil. Not everyone who crosses the Moral Event Horizon become this, but a CompleteMonster has definitely crossed it -- at least once.

* EarthShatteringKaboom: Destroying an entire planet is a major line-crossing.

* HateCrimesAreASpecialKindOfEvil: Violent bigotry is treated as being especially awful.

* HeWhoFightsMonsters: He who seeks revenge against the villains should be wary, not to get so influenced by them that he crosses the line and becomes a villain himself.

* CrossesTheLineTwice: When these actions are [[BlackComedy played for laughs]].

** PimpingTheOffspring: A parent prostituting their own children is almost always this.

* PunishedForSympathy: In a cultural sense, a character showing sympathy for someone who has crossed it is considered just as bad as the line-crosser. That being said, this trope is also a good way of showing why a culture or world [[ItsBeyondSaving is corrupt beyond redemption]] if a character is punished for sympathizing with a WoobieDestroyerOfWorlds or someone who was wronged by the system in the first place.

* PunishedForSympathy: In a cultural sense, a character showing sympathy for someone who has crossed it is considered just as bad as the line-crosser.

The Moral Event Horizon is the deed that renders a villain irredeemable. Named after the event horizon of a black hole, it is no longer possible for a villain past the Moral Event Horizon to be redeemed. If they try to, it will be [[ReformedButRejected rejected]], {{ignored|Epiphany}}, or [[HeelFaceDoorSlam otherwise prevented from succeeding]]. If they do redeem themselves, then they never actually crossed it in the first place.

* WidowMistreatment: Treating a someone worse after the vulnerable sitiation like the death of their spouse is a good way to cross the line.

* TautologicalTemplar: Even worse offenders at crossing the line than the KnightTemplar because they believe ''everything'' they do is good, no matter how monstrous.

* YouHaveOutlivedYourUsefulness: [[LackOfEmpathy Treating others as expendable pawns]] is bad enough, but murdering them after they do what you want is a whole other level of depravity.

** ''MoralEventHorizon/UntilDawn''

* SentencedWithoutTrial: Some (not all) would argue that people who cross this line are so obviously guilty that putting them through a trial would be a waste of time.

* NuclearWeaponsTaboo: Ordering the use of a nuclear weapon is very often portrayed as an irredeemably evil act, as they cause indiscriminate destruction on such a massive scale that anyone with a functioning moral compass would see the results they bring as a PyrrhicVictory ''at best''.
