Why do serial killers kill?

Serial killers are a fascinating phenomenon. Why do they kill? What drives them to commit such heinous crimes? There is no simple answer, as each case is unique.

However, there are some common motives that have been identified. In some cases, the killer may be motivated by a desire for power or control. In others, they may be driven by a need to satisfy their own twisted sense of justice. And in some cases, the murders may simply be a way to release their own inner rage or frustration.
