Gaius

Paul knew that anyone he converted would be tortured and killed. Heck, his original job (until he saw the light) was to kill Christians.
He must have wrestled internally with the matter. “I’m going to convert you, and if I am successful you will be tortured and killed. But if I leave you alone, you and your family will be fine.”
Any biography of St Paul (including Acts) would be incomplete without making reference to how St. Paul dealt with thus issue.
Lukes (later) death is unrecorded but tradition holds that he too was martyred and the ancient Romans were not gentle in their methods of martyrdom.
