The connotation of the word "charged" provides an 'aggressive' or 'offensive' tone to the sentence.
Explanation:
The word "charged" exemplifies the connotation i.e. "burden" instead of being "instruction". As Degol had just reached and he's been instructed with a list of chores which sounds itself very offensive. <em>Thus, the connotative meaning converts the tone of the sentence into an annoying and obnoxious one. </em>The usage of "charged" adds to the intensity of the situation and casts the emphasis and emotion to the statement.
Macbeth is very calm, almost like he doesn't care at all. He says that she was going to die someday anyway. He has lost everything and this does not bother him.
