Graffiti Tourist: When in Rome

A tourist from the UK carved his name into the Roman Colosseum in 2023 ~ approximately 2,000 years after it opened to visitors.  He claims he didn't know how old the Colosseum was but he sure is sorry that all of Italy and most of Europe wants to see his blood splashed against the Colosseum floor in exchange for carving "Ivan & Haley 4Evah" onto the walls.

It turns out that graffiti is nothing new and people largely had the same d*ck jokes 2,000 years ago as they do today.  So should this UK tourist be thrown to the lions or is his apology good enough to stop Italian justice from taking its vengeance out upon him?
