Why did Dominican friar, Jacques Clément,( catholic?) kill a catholic king? for

Question:This was the time of the wars of religion in France.
The Duke of Guise controlled Paris, was popular, and Paris was very Catholic.. His brother, a cardinal, had been murdered and Henry III was blamed.
Henry III (the ruler whom Clement would kill) was nominally a Catholic, but in his early life had flirted with becoming protestant, and in fact had signed agreements with Protestants previously during his reign which gave them more freedom, although he was forced to later renege on some of these agreements. At least you could say he was not rabidly Catholic.
He was on the verge of attacking Paris and the popular Duke of Guise with an army. He was also an ally with the man who would be his successor,an out and out protestant. (Henry IV.) Thus though technically a Catholic, Henry III was seen as opposed to other, less wavering Catholics, such as Jacques Clement.
Remember especially that quote attributed to Henry IV: Paris is worth a mass. In other words, he was willing to change religions for the sake of power. And to repeat: Henry III and IV were allies--birds of a feather, you might say.
For some, religion is, er, religion. For others, politics.

You seem to be asking if the assassination of a Catholic king by a Catholic friar is morally defensible. The answer is, of course, no, it is morally wrong, regardless of the religious quavering of Henry III. I am a Catholic, so I'm not saying this from an anti-Catholic viewpoint. In Catholic theology, both then and now, the friar's action was considered murder. I am not familiar with this particular piece of history, so I don't know what became of the friar-- if he was disciplined or praised. But morally, his action was wrong.
