Considering Trump's general and historical appetite for risk, as well as his triumphant return to the White House despite multiple indictments that almost sent him to prison, and having fairly recently survived an assassination attempt where he was literally within an inch or so of losing his life, Trump is most likely currently of the belief that he has been "chosen by God."
Trump might be cognizant of the risks, but they're definitely being downplayed, if not largely ignored inside his head.
So Trump likely believes the costs will be minimal.
