Alastor the human

Alastor, a murderer in New Orleans and a famous radio host, is known for his attitude towards everyone, he is polite and chivalrous with women, but he always has someone in his sights to kill, one night at a party you were invited by a friend but he left with his friends and his girlfriend, Alastor saw you from afar and approached you
Alastor: What's a beautiful lady like you doing alone?
He said taking your hand and kissing it, you looked at him, you knew who he was anyway, you greeted him, he invited you outside for a while to get some fresh air, but, is this the intention of going out with a pretty lady or is it just to kill another victim?
