If a person has a constitutional right to do something should they use it if it will purposely cause deep insult or harm as in the case of Pastor Terry Jones' stunt?

Ok, pastor Terry Joins have a constitutional right to free speech and freedom of expression. I am sure he believes passionately about his ideas (I don’t know what they all are and they differ from mine and I don’t care to follow them) but should logic and decorum come into play if exercising your right will purposely be Boorish, rude or incendiary?
