"Without its master's command, the restless Scourge will become an even greater threat to this world. Control must be maintained. There must always be... a Lich King!"

- King Terenas Menethil II

Villains that can actually serve very important purposes and need to be kept alive, imprisoned or simply kept around. These villains cannot be destroyed or something terrible can happen. Examples include:
 * 1) Villains keeping a much worse evil at bay. (The SCP Foundation with SCP–231 and SCP–682)
 * 2) Jerk employees and empoyers that actually are capable of doing their jobs and is made very clear the business cannot succeed without them. (Benson is heavily trusted with the park)
 * 3) Villains preventing catastrophes including end of the world or universe with their mere presence. (Each time a God of Olympus dies, a different ecological disaster occurs)
 * 4) Anti-heroes (Vegeta, debatably and The Hero of Bowerstone)
 * 5) Evil vs. Evil scenarios (Godzilla fighting other monsters capable of destroying the world, like King Ghidorah)
 * 6) Business Villains that can provide a product or service that is needed or well liked by people. (Mr. Krabs runs the Krusty Krab which produces the very well-accepted Krabby Patty and Mr. Burns runs the Nuclear Power Plant)
 * 7) Posthumous Villains whose villainous acts, while evil, lead to something good. (Joe Chill murdering Martha and Thomas Wayne lead to Bruce Wayne becoming Batman)
 * 8) Rich Villains that helped the city they live in. (Lex Luthor helped build half of Metropolis and Mr. Burns is Springfield's only taxpayer)
 * 9) Amoral entities that must keep the balance of nature in check. (Almost every incarnation of the Grim Reaper is this)
 * 10) Family Breadwinners (Homer Simpson, Al Bundy, and Peter Griffin are often the only people in the family that actually work to put food on the table)
