We test the chronology protection conjecture in classical general relativity by investigating finitely vicious spacetimes. First we present singularity theorems in finitely vicious spacetimes by imposing some restrictions on the chronology-violating sets. In the theorems we can refer to the location of an occurring singularity and do not assume any asymptotic conditions such as the existence of null infinities. Furthermore, introducing the concept of a non-naked singularity, we show that a restricted class of chronology violations cannot arise if all occurring singularities are non-naked singularities Our results suggest that the causal feature of the occurring singularities is the key to prevent the appearance of causality violation.
