Slum Reaper may be the creature its controller sacrifices for its own ability.

If any player controls no creatures, that player simply doesn’t sacrifice anything. Each other player still sacrifices a creature.

As Slum Reaper’s ability resolves, first the player whose turn it is chooses a creature they control, then each other player in turn order does the same, knowing the choices made before them. Then all the chosen creatures are sacrificed at the same time.
