We show that singularities necessarily occur when a boundary of causality violating sets exists in a spacetime under physically suitable assumptions, except for the global causality condition in the Hawking-Penrose singularity theorems. Instead of the global causality condition, we impose some restrictions on the causality violating sets to show the occurrence of singularities.
