He wears the finest clothes, has the finest foods, lives in a palace with servants where his ever need is catered to and DOES NOT fear assassination....he has his own secret service.

He is no more closely examined than any other powerful person who leads a semi public life.
Well, kinda... He does have a fear of assassination - he goes about in a Popemobile without the covering. About a month ago, a man got through the security lines and was feet from the Pope.
And our last Pope had a serious attempt on his life.
