The criteria for serail killer says:

Serial Killers include villains who personally killed at least three people . They usually have "cooling off" periods in which they won't commit any murder.

Do NOT include generic Cataclysmic villains (e.g. Frieza or Abraxas) who butchered without distinction entire worlds, galaxies, universes or even realities, as this category is meant for villains who target individuals. (Such villains can still qualify if, aside destroying worlds, they also have killed multiple individuals who stood in their way.)

That last point is what allows him qualification.
