At the beginning of the play Much Ado About Nothing, Benedick portrays elements of self-confidence, which could easily be mistaken as "cockiness".
By stating "but I am loved of all ladies", this straight away gives the impression that he is very self-confident and slightly boastful.
Benedick repeats the words "Ill never", he maybe repeats this, to draw attention to the fact that he will never take a wife and wants it to sound believable.
Benedick repeating this phrase often could also be seen as him reassuring himself.
I think Shakespeare uses certain devices to convey Benedick's excitement and shock. " Bendick repeatedly uses words, which are marriage related.
First of all, a short burst of really short sentences is used. This shows he may already be thinking about it, and that even though its not on his tongue, he's thinking about it.
So it may not come as a complete surprise to the audience.
The audience may also find it amusing that Benedick can change his feelings and principles at the drop of a hat, just by finding out that one woman has taken a liking to him.
Benedick states, "is't come to this, in faith hath not the world one man but he will never wear his cap with suspicion. ", by stating this, Benedick shows how horrified he is at the concept of Claudio taking a wife and totally against the idea.
Benedick cannot see anything particularly special about Hero, he expresses his feelings about her when he mentions, "Why I'faith, methinks she's too low for a high praise, too little for a great praise, too low for a high praise, and too brown for a fair praise", making his feelings about her crystal clear.
